This is very easy. Your subject line contains the key. A nested for loop is simply one loop inside another, e.g.:
Code:
for (int i=0; i<10; i++)
{
    for (int j=0; j<10; j++)
    {
        printf("%d %d\n",i,j);
    }
}
Start with a for loop that displays any number N of *'s (hint: a printf that displays one star inside a loop will do it). Change the value of N and check the program prints the correct number of *'s.

Then put that for loop into another for loop and vary N from 1 to the relevant maximum.

It's as simple as that!
