    Stick an int n = 0 at the start, then in the loop put n++;
    Each time the loop goes through n is incremented, thus n == number of times looped.

    int n;
    cin >> n;

    I enter 'foo' when it asks for input, the cin fails, nothing is written to n, it is 'empty' (aside from the garbage value from not initialising it).

    That code looks to be a snipper from a recursive function, which calculates the x^n.

    What it does is you call the first function, with 2^3 say.
