No articles, references or a new thing to learn ? :D

Samuel Shokry 30-May-16 23:13pm View

Well, thank you,, but actually I want to learn new things and become better, just to know what is wrong and I'll try to solve it myself, or even to change the algorithm completely, some articles, or references would be great.
by the way, I remember another programming problem, and used this technique, but I failed, I just learnt another one, and I got accepted, but because I didn't learn what was wrong, I failed again. Honestly, It's all about learning and nothing else..

You know what, you answered the question that i wanted to ask but prefered to pose a simpler and straightforward one. Simply, You rock !! Thank you ☺☺☺

Samuel Shokry 12-Dec-15 13:40pm View

First of all thanks for your reply.
I have googled it, and I understood that it is a pointer to the inner data, but what about calling delete, why doesn't it cause any problem to the string object ?

I'm using code blocks 13.12 IDE with gcc I'm sure about it's version. But does it treat a static const int with initialization only as if it was an enum ?

Thanks, You rock !!

I mean why could I take the address of a value in an enum but I could not do that for a static const int in-class initialized without an outside-class-definition ? I wish it become more clear now :)

Sam.

Thanks, I have got it!

Samuel Shokry 11-Aug-15 13:13pm View

This means that every constant in code, such as 6, 7.012, "Hello World", has a place in memory, and the value in this place could not be changed until the place is reserved by an object or a variable, Right ?

Samuel Shokry 5-Aug-15 23:43pm View

I think I have got it but why function like strcpy doesn't work and cause a runtime error ??

Samuel Shokry 4-Aug-15 23:35pm View

Do you mean that I have passed a copy of pointer str and "Hello" string as well ?? But I have a misunderstanding, when I used the debugger I have found that both of the two pointers have a the same address, does not that mean that both of them points to the same thing ?

Samuel Shokry 29-Jul-15 23:17pm View

I will.

Samuel Shokry 29-Jul-15 13:22pm View

Thanks you helped me.

It is Practical C++ programming by Steve Oualline. He wrote exactly 3 lines about it plus 7 lines of simple example that I haven't understand well.

Samuel Shokry 9-Jul-15 22:20pm View

Actually I have finished reading it.

Samuel Shokry 9-Jul-15 21:24pm View

Thank you so much Stefan, I have got it now.

Samuel Shokry 9-Jul-15 21:23pm View

Oh right, He gave the solution. Thanks

Samuel Shokry 8-Jul-15 17:37pm View

Umm thanks.

Samuel Shokry 8-Jul-15 9:43am View

Oh thanks, but what about this ?
"itr = find( student_roster.begin() , student_roster.end() , "John" );"
I'm just curious about this line, is it not legal in C++ ?

Samuel Shokry 8-Jul-15 9:42am View

Have you read the code ? Do you know why this line of code doesn't work ?
"itr = find( student_roster.begin() , student_roster.end() , "John" );"
Of course, I know the usage of the member function find of the container map, I'm just curious about the line that I have written above in this comment.
is it not legal in C++ ?

Samuel Shokry 8-Jul-15 4:32am View

That's it , I guess :
e:\programs\codeblocks\mingw\bin\..\lib\gcc\mingw32\4.7.1\include\c++\bits\stl_algo.h|135|error: no match for 'operator==' in '__first.std::_Rb_tree_iterator<_Tp>::operator*<std::pair<const std::basic_string<char="">, std::basic_string<char> > >() == __val'|

Samuel Shokry 8-Jul-15 4:30am View

I know how to use this about what something like that in my code, it works with vectors by the way.

Samuel Shokry 3-Jul-15 22:36pm View

I'm sorry for lack of clarity, my problem is I have such a number
37107287533902102798797998220837590246510135740250 in a file, I want to read just the first ten digits, so I used a char to read each digit, but I had to read also the next 40 digits without adding them which waste a lot of time in the case of more data to read, how to skip that or to go to the next line for example. I wish that my question is clear enough this time.
Thanks, Samuel.

Samuel Shokry 2-Jul-15 11:48am View

Yes, I though I had to rewrite it in a better way, I have a lot to learn about code design and alogrithms. Thanks a lot.

Samuel Shokry 2-Jul-15 11:46am View

I used this if statement in my debugging no more.
Yes, I need more work I have just been programming for 2 months, I'd work hard.
Thanks a lot for help.

Samuel Shokry 2-Jul-15 1:43am View

I'm very sorry for that relatively long code

Samuel Shokry 1-Jul-15 14:26pm View

Thanks

Samuel Shokry 24-Jun-15 8:54am View

Thanks That's great

Samuel Shokry 24-Jun-15 8:54am View

WOW !! I thought I had a few problems now I have a lot of them, Thank you very much you helped me a lot :)

Samuel Shokry 24-Jun-15 8:42am View

I would work hard the next time

Samuel Shokry 22-Jun-15 9:07am View

I used long long int instead of long and it worked for me :)

Samuel Shokry 21-Jun-15 15:59pm View

I used it in my code

Samuel Shokry 20-Jun-15 17:10pm View

Yeah, Thanks a lot. I forgot it .

Samuel Shokry 18-Jun-15 16:15pm View

I'll try, Thanks for help. ^_^

Samuel Shokry 18-Jun-15 13:10pm View

Thanks for your help, but what this code ? why it doesn't copy items to the vector that it should be copied.

Samuel Shokry 16-Jun-15 17:58pm View

Thanks a lot :)

How to delete an element from the linked list chosen by the user. That's it ^_^

Samuel Shokry 8-Jun-15 21:57pm View

Thanks a lot

Samuel Shokry 8-Jun-15 21:56pm View

An element that is entered by the user from the linked list
