Need some help with loop descriptions.

[aaronfue]

I've been trying to figure out what is going on within these two loops? Assuming all variables were of type int, can anyone describe what is happening? I ran them both but am not sure how the answers were calculated.

	
i =1;
while (i*i < 10)
{
    j = i;
    while (j*j < 100)
    {
        cout << i + j << endl;
        j *= 2;
    }
    i++;
}
cout << “\n*****\n”;

i = 0;
do
{
    j = i * i * i;
    cout << i;
    do
    {
        k = i + 2 * j;
        cout << j << k;
        j += 2;
    }
    while (k <= 10);
    cout << endl;
    i++;
} while (j <= 5);
