#include <iostream>

using namespace std;

int get_number(void);
void print_divisors (int input_integer);
bool user_repeat (void);

int main (void)
{
int input_integer;

do
{
input_integer = get_number();
print_divisors(input_integer);
}
while (user_repeat());
}

int get_number(void)
{
int num;
cout<<"Enter a number\n";
cin>>num;
if(num<1)
cout<<"This number is unacceptable. Please enter another number"<<endl;
="" else
="" return="" num;
=""
}

void="" print_divisors(int="" input_integer)
{

="" for(int="" factor="1;factor<=input_integer;factor++)
" {
="" if(input_integer%factor="=" 0)
="" cout<<factor<<"="" ";
="" }
}

bool="" user_repeat="" (void)
{
="" char="" answer;
="" if((answer="" !="y" ||answer="" )||(answer="" ))
="" cout<<"please="" respond="" with="" y="" (or="" y)="" for="" yes="" and="" n="" n)="" no"<<endl;
="" do
="" cout<<"would="" you="" like="" to="" try="" another="" integer="" (y="" n)?\n="" cin="">>answer;;
if(answer=='Y' || answer == 'y')
cout<< main();

}while(answer =='N' || answer == 'n');

}

I want this output
Please enter a positive integer: 18
18 9 6 3 2 1
Would you like to try another integer (Y/N)? y
Please enter a positive integer: -44
-44 is not a positive integer.
Please enter a positive integer: 109
109 1
Would you like to try another integer (Y/N)? m
Please respond with Y (or y) for yes and N (or n) for no.
Would you like to try another integer (Y/N)? N

So that everyone can pay attention to this information.

Don't forget to tell what is the problem with the code.

Dave Kreskowiak 14-Aug-20 23:28pm

You mean your homework assignment says you can't use recursion.

Isaac David 14-Aug-20 23:32pm

yes

Richard MacCutchan 15-Aug-20 4:06am

You could start from the other direction. Divide by 2, then 3, then 4 ... continuing until you get to the value of number / 2. Obviously as you build your list you can ignore the ones that have been found already. You can also avoid all the even numbers if the original number is odd.

I see your code in comments, note that was corrupted during paste in comment.
The code contain numerous syntax errors, without even speaking about its logic.
A few rules:
- Never call main() from any place in code.

C++

cout<< main();

- Any command ends with a semicolon

C++

cout<<"would you like to try another integer (y n)?\n cin>>answer;;  // 2 semicolon at the end is an error
// prefer
cout<<"would you like to try another integer (y n)?\n; cin>>answer;

- Advice: do not put multiple command on same line of code, it works, but it also make code more difficult to read.

C++

cout<<"would you like to try another integer (y n)?\n ;
cin>>answer;

- Quotes always goes by pairs

C++

cout<<"would you like to try another integer (y n)?\n";
cin>>answer;

-

C++

int get_number(void)
{
	int num;
	cout<<"Enter a number\n";
	cin>>num;
	if(num<1)
		cout<<"This number is unacceptable. Please enter another number"<<endl;
		// this code path is missing a return command
	else
		return num;
}

Advice: rewrite the program as a single piece of code in main() until it works, then analyze the code to see which part can be made a function (the part that make the function will be replaced in main code by the function name.
How to make a function for a piece of code is a skill you have learn.

We are more than willing to help those that are stuck: but that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.

So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.

Hi OG,
code is in comments.

OriginalGriff 15-Aug-20 2:24am

Yeah, I saw.
Did you read it?

cout << main();

OMG ...

Patrice T 15-Aug-20 2:30am

Yes I know :) typical from very beginners.
But at least he did some work.

Isaac David 20-Aug-20 12:30pm

yo man its not my grades. Its just a pratice qns. The program i sent is my version of the program. Im not getting paid either
