formatting an integer output using ostream

Question

I am trying to find the equivalence of %2d using cout << <<endl format. how can I do that?

Answer 1

You need setw

Answer 2

The header <iomanip> contains the stream manipuator setw:

cout << setw(2) << myint << endl

You may also be interested in setfill:

cout << setfill('0') << setw(2) << myint << endl

will pad with a 0 instead of a space.
