C++ How can I do a nested for loop for *?

Umm, so I got this assigned for my C++ homework and I don't understand how do it.

// Write a code block that uses nested for-loops (and no

// if-statements or switch-statements) to produce this sequence of

// 4 lines of asterisks (that is, the char value '*'):

// *

// **

// ***

// ****

Can anyone help out?

    The point is the consition part of the second for loop (m < n + 1):

    for(int n=0; n< 4; n++)

    {

    for (int m=0; m< n +1; m++)

    {

    cout << '*';

    }

    cout << '\n';

    }

    for (int i = 1; i <= 4; i++) {

    for (int j = 1; j <= i; j++) {

    cout << "*";

    }

    cout << endl;

    }
