how to print last increment

Question

i use increment in gcd program

Answer 1

You could also just use cout << i++; This way you are printing I, THEN incrementing it. for example.

int i = 2;
cout << i++ << endl;
cout << i << endl;

what is printed:
2
3

Answer 2

I think what you want is this
cout<<++i;
but if not, be a little more specific
