    ostream

    In C, if I want, for example, to print a variable as a floating point, at least 6 wide and 2 after decimal point, I use : printf("%6.2f", var);
    How can I have the same effect on C++, using cout << ?

    Hi,

    you have to use

    cout << fixed(2) << var;

    to display only 2 number after the decimal point
