Thread: What I am doing wrong here?

Here is my code:

Code:

#include <iostream>
#include <iomanip>

using namespace std;

//function prototypes

int getNumber();
int printnumPerLine();
void printResult(int, int);

int main()
{
int num;
int numPerLine;

num = getNumber();
numPerLine = printnumPerLine();
printResult(num, numPerLine);
}

//get input from keyboard and return it to caller
int getNumber()
{
int num;
	cout << "\n\nPlease enter a non-negative number: ";
	cin >> num;
	
	return num;
}

int printnumPerLine()
{
	int numPerLine;

	cout << "\nHow many numbers per line? ";
	cin >> numPerLine;

	return numPerLine;
}
//print our result
void printResult(int num, int numPerLine)
{
	int i = 0;

	do{
		cout << setw(4) << i;
		i++;
	} while (i<=num);
		
	if(i % numPerLine == 0){
			cout << endl;
	}
	cout << endl << endl;
}

It is suppose to print user defined number of lines, but for some reason its not working. I had been using for loop and I can make it work in for loop, but I need to learn do while too. Please let me know what am I doing wrong here. The problem is at the if statement I guess.

Thanks

Already got the code handed to him here. Good thing you didn't have to think too much, huh?
