formatting an integer output using ostream

I am trying to find the equivalence of %2d using cout << <&l开发者_运维百科t;endl format. how can I do that?

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.

You need setw
