Here's a link to simple program, to display the words "Hello World". Take a look at it and see how it differs from what you have in terms of your main() function.

C++ "Hello, World!" Program[^]

Then take a look at how functions work,

Sample code that works?

jeron1 16-May-24 12:34pm View

OK you can take a look here for how functions are used.

I suppose you could use the code inside the function, in your main(). Nevertheless, do you know what to do (is required) after reading data from the file?

"The program doesn't do anything" is not a lot to go on. Can you set breakpoints and step through the code? or add lots of printf()'s? Is your list being populated properly? Problem in the felsazabadit() function?

jeron1 3-Nov-23 10:35am View

p starts out is a pointer to array (ray) index 0. You then set the contents of the memory that the pointer points to, to the contents of ray[2] which is 6. Your pointer p is still pointing to array index 0 at this point. You print the contents pointed to by p (array index 0) which is now 6, you increment p so it points to array index 1, which contains the value of 4.

I am not sure I understand your explanation of the issue, but I don't see where you're looking for the "L3 End of record", the point at which I believe you want to process the received information. Also, if your data is received in multiple packets the buffer will probably be overwritten on receipt of the 2nd and 3rd.... packets, though there is not enough detail to know.

jeron1 27-Apr-23 15:40pm View

Can't imagine that this will compile, and not sure what the question is but there should be a comma instead of a period in the following;
static bool f(int q. int64_t y) // <== should have comma

Also there is a space between 'size' and 'of' in the following;
static const int N = sizeof(my_data)/size of(*my_data);

Not sure if this will help but generally, initializing an array looks something like,

Your parms array initialization seems wrong.

Is there a specific question? Where are you having problems?

jeron1 10-Mar-23 15:47pm View

The comparison operator used in the if statement should be == not =. The single equal sign is an assignment operator, which is setting the z variable to whatever is after the equals sign. Also, the result of the division is going to be an integer (no fraction), perhaps not what you wanted.

jeron1 10-Mar-23 13:33pm View

You're probably going to have to add the implementation of the queue class to the original post, use the green 'Improve question' option.

Is it any different if you specify Serial.begin(9600); like the example you got this from?

jeron1 28-Feb-23 11:59am View

It doesn't really matter what the algorithm does as the code is not compiling, you have a number type mismatch errors and syntax errors that need to be resolved first. Start with the first warning/error and work your way down.

jeron1 24-Feb-23 10:23am View

Generally start with the first error, go to that line and the lines near it and see if there is a syntax error. Hint, most lines require a semicolon at the end.

Sorry, I have no idea what you are looking to do, which is why I suggested showing what is it that you want displayed (output) and entered (input) and the order that it happens, at the console. Maybe someone could figure out what it is that your goal is.

jeron1 13-Dec-22 11:12am View

Maybe edit the original post to show a simple example of what you would like to see (both inputs and outputs) at the console.

jeron1 12-Dec-22 13:34pm View

At this point, based on your attempted use of arrays and their indexes, and the the fact that the code does not compile, it seems a bit beyond your current level. Try simplifying things, maybe make your class simpler, write a loop that populates an array with data, then write a loop to output the data. Then try doing these things in a function.... build slowly from simpler to more difficult. Perhaps learn how to use a debugger, you will learn a LOT using a debugger.

jeron1 7-Dec-22 12:44pm View

Before accessing elements of the vector using [] brackets, make sure that whatever is within those brackets is valid. I'm talking about the first couple line of the compute() method.

jeron1 7-Dec-22 12:06pm View

You don't need an array size variable for use in the compute() method, you have a vector, use it's size() method.

jeron1 2-Dec-22 15:40pm View

If you can't solve it on paper, there's no point trying to code it. Also, I'm guessing googling the subject would yield lots of examples.

Please just update your original post and not create a new 'Solution'. Post the code that you have written, along with a specific question. The 'if' statement you've posted is wrong for multiple reasons. Read your book and at least try to emulate the syntax.

jeron1 23-Nov-22 10:20am View

How about you just check the integer range, isdigit() expects a character that is casted to an int you don't have characters. I am not going to speak to your use of goto's and the structure of your logic, as I am sure others will.

if ((select >= 1) && (select <= 6))

jeron1 23-Nov-22 10:07am View

First, you should update your original post with this attempt and not create a 'solution'. Second. you define an int variable 'bins', that are are treating like an array of int's, that can't work. If you want an array of integers declare and initialize one;

int bins[5] = { 0, 0, 0, 0, 0 };

jeron1 22-Nov-22 13:02pm View

You'll need variables to hold the counts (5 of them). So you iterate through the array, calculate the percentage for a given grade, then increment the appropriate count variable based on that percentage, perhaps using if, elseif, else. When complete, print the appropriate label for example "1.0" or "1.5", then create a loop (a for loop maybe) based on the associated count variable to print the x's.

jeron1 22-Nov-22 12:35pm View

What is your question?

jeron1 18-Nov-22 12:13pm View

What is it doing (or not doing) versus what is expected?

jeron1 10-Nov-22 14:15pm View

Could you solve this on paper?

jeron1 10-Nov-22 13:19pm View

You could try removing the comma between the %d's if the scanf call.

jeron1 10-Nov-22 11:34am View

You are executing every if statement, eventually you always get to the last one, if d is not equal to 8, you will perform the else statement, and print "Invalid value". You could just return after printing "American masculine citizen", "American feminine citizen", or "Foreign masculine citizen". There are several other ways to handle this as well.

jeron1 9-Nov-22 16:00pm View

Update your original post to reflect the current state of the non-working code.

jeron1 7-Nov-22 13:37pm View

Maybe use the (absolute value) abs() function in your printf statement?

printf("Suma cifrelor este %d",abs(sum));

jeron1 4-Nov-22 16:44pm View

 put all the vars at end of the print f ... just keep their type "%s"

So we are adding a %d to that as well.

jeron1 4-Nov-22 11:59am View

"just keep their type "%s" "
But variable 'umur' is declared as an int.

jeron1 4-Nov-22 10:52am View

You should have your format string, then your variables when using the printf() function
try something like,

printf("\n%s\t |\t %s |\t %d", k1.idpegawai, k1.nama, k1.umur);

jeron1 28-Oct-22 13:54pm View

True, but at some point you are counting on a return value;

p= prime(n,n/2); // you are expecting a return value here
if(p == 1) // in order to test it here
{
printf("Yes");
}

jeron1 28-Oct-22 10:18am View

prime() is supposed to return an int, nothing is being return right now.

jeron1 7-Oct-22 17:28pm View

"does not display every time I run my code" as in the word "Quick" is not displayed? or displaying the wrong values, or something else. Is your quickSort() executing the return statement as it should? Running with a debugger would tell you pretty quickly.

jeron1 7-Oct-22 12:17pm View

isdigit() is looking for a character type, try changing 'value' and 'matrix' (I am guessing matrix type is int) to be type char, and see what happens.

jeron1 6-Oct-22 13:26pm View

Just a note, if a function does not return a value it should have 'void' as the return type. Compilers might assume a return of void if no type is there, but for readability sake similar to;

void postfixeval()

jeron1 18-Aug-22 13:41pm View

I would update your original post with your current version of code, then try and give a specific scenario with a specific input, and the desired output, and the actual output that you are seeing. There are many people here that are willing to help if given proper data to work with.

jeron1 18-Aug-22 13:08pm View

It shouldn't compile, you call

prefixeval(prefix); // calling with input parameter 'prefix'

int prefixeval() <== No input parameters specified and should return an int

Do you have a question?

jeron1 25-May-22 16:24pm View

Can you solve this on paper?

jeron1 20-May-22 15:42pm View

Care to elaborate?

jeron1 5-May-22 11:28am View

Move the cout line after you've done your counts, not before.

jeron1 4-May-22 18:33pm View

Also, you should take a look at your test for consonant, what if the letter is 'e' for example. It's between 'a' and 'z', and you're incrementing the consonant variable.

jeron1 4-May-22 13:16pm View

Looks like you are outputting the counts before you try and calculate the counts.

jeron1 2-May-22 12:23pm View

Can't say I saw that one coming...

The Add and Assign (+=) operator.

totalmoney += add[i].total;

equates to

totalmoney = totalmoney + add[i].total;

You tagged this with C++...

"i already tried but dont get it"

What did you try?
You should show your code.

Read the contents of the file into memory, remove the word (or character) from memory, then write the modified memory to the file.

jeron1 19-Apr-22 12:14pm View

You haven't shown any code so no one can comment on it. Can you solve this on paper?

ANSI vs Unicode issue?

Well said. :thumbsup:

Is there a specific question?

"Let's work to help developers, not make them feel stupid. "

Near as I can tell, he did. Asking for clarification as Richard did is a necessity in many instances, and having more specific data would allow more eyes to see what you are seeing, and may ultimately lead to a solution. I saw no disparaging remarks in his response, no need to get defensive.

" for the question i ask"

and your question is?

jeron1 5-Apr-22 11:46am View

Your question is?

jeron1 5-Apr-22 11:38am View

You have not asked a question. Just an observation, one would generally call srand(...) before rand(). What are you attempting to do with the '% 100' portion of your rand() statement?

jeron1 4-Apr-22 20:13pm View

:thumbsup: Indeed!

"&& (pw,password)==0"

What is "(pw,password)" supposed to do? Do you want a second string compare? If so, do a second string compare;
if(strcmp(id,username)==0 && strcmp(pw,password)==0)

Start looking at your braces near the top of your while(t==true) statement (which could just be while(t)).

jeron1 24-Mar-22 11:02am View

It might help if you add the node struct definition to the original post.

jeron1 24-Mar-22 10:42am View

Maybe you could explain what exactly doesn't work, and post a small, testable example of the file data.

jeron1 21-Mar-22 16:35pm View

I don't see any code. What do you want to display and where do you want to display it?

jeron1 21-Mar-22 11:22am View

You should post the entire code if possible.

jeron1 21-Mar-22 10:18am View

You have not actually asked a 'C' question, do you have one?

jeron1 18-Mar-22 10:34am View

scanf("%s",&name[20]);

You sure about that?

jeron1 16-Mar-22 13:11pm View

"float=0.0;" is not a valid statement (no variable name), probably will not compile.

add a variable name, something like,

"float abc = 0.0;"

jeron1 15-Mar-22 11:21am View

That's 0xC0000005 Access Violation, probably an invalid pointer. Can you step through that function, and see what line it fails on? (assuming it fails in that function)

jeron1 10-Mar-22 11:56am View

I would initially 'brute force' it, then try and optimize only if necessary. If you have specific questions during that process, feel free to ask them here.

Comparing doubles can be tricky, take a look at,
https://www.tutorialspoint.com/what-is-the-most-effective-way-for-float-and-double-comparison-in-c-cplusplus
For a way to method to compare.

I know (hence my vote), but for some reason, I am feeling somewhat optimistic today. A condition I am not used to, trying to remedy as we speak.

jeron1 24-Feb-22 13:03pm View

What is the C question?

jeron1 17-Feb-22 17:45pm View

Just a guess, looks like you're setting a CBrush object to MenuInfo.hbrBack, the doc says it should be an HBRUSH.
MenuInfo.hbrBack = *NewBrush;

You could try using the HBRUSH operator something like;
MenuInfo.hbrBack = (HBRUSH)*NewBrush;

Not sure if it will help.

jeron1 9-Feb-22 9:58am View

Agreed.

jeron1 8-Feb-22 13:34pm View

That's actually a scary thought, basic std::vector operation altered by the size and/or complexity of the project? Doesn't sound right to me.

jeron1 7-Feb-22 17:22pm View

'typo' D'oh! Good catch.

jeron1 7-Feb-22 16:32pm View

You can edit your original post to include all the requested information.

jeron1 7-Feb-22 12:50pm View

Sorry, I am not going to follow the link, can you post your current code and describe what it is doing that you believe is incorrect? You can edit your original post for this.

jeron1 7-Feb-22 12:22pm View

Just declare the vector, and add things to it;

std::vector<int> arraych; // Declare, after this point size should be zero
int theInt = 42;
arraych.push_back(theInt); // add as needed , size should be 1 after this

jeron1 4-Feb-22 15:17pm View

Post what you've tried, and point out which portion is giving you trouble.
