Spacing in count new lines

[BGA6444]

The program is supposed to output 10 prime numbers per line, and it does. The problem is the spacing varies between the lines. Anyone know how to fix it?

#include <iostream>

using namespace std;

bool coutprime(int);

//--------------------------------------------------
int main() //cout prime numbers till 100
{
	int line = 0; //10 per line

	for (int n = 2; n <= 542; ++n)
	{
		if (coutprime(n))
		{
			cout <<" " << n; 
			line++;
		}
//new line after 10
		if (line % 10 == 0)
		{
			cout << "\n";
		}
	}
	system("PAUSE");
}
bool coutprime(int n)//function
{
	bool prime = true;
	for (int c = 2; c <= n / 2; ++c)
	{
		if (n % c == 0)
		{
			prime = false;
			break;
		}
	}
	return prime;

}
