Seperating two output lines by a certain number

[sosupin]

This is my code, I have everything done and all I need to do is figure out how to get my outputs of HTHTH to 10 per line. I cant figure it out and its driving me crazy

#include<iostream>
#include<cstdlib>
using namespace std;

int tossingCoin();

int main ()
{
    int coin, num, tails = 0, heads = 0;
    for (num = 1; num <= 20; num++)
    {
        coin = tossingCoin ();
        if(coin==0)
        {
            cout<<"T ";
            tails = tails + 1;
        }
        else if(coin==1)
        {
            cout<<"H ";
            heads = heads + 1;
        }
    }
    cout<<endl;
    cout<<"Heads: "<< heads<<endl;
    cout<<"Tails: "<<tails<<endl;

}
int tossingCoin()
{
    return rand( )%2;
}

for (num = 1; num <= 20; num++) {
    coin = tossingCoin ();
    /*...
     *...
     */
        heads = heads + 1;
    }
    if (num % 10 == 0)
        std::cout << std::endl;
}
