    %3s equivalent for C++

    what happens if i have a char array [20]
    and i want to print only the first 3 letters of the string

    what c++ function would i use?

    the idea is that i have a ssn [10]
    and i want to display it as 1234-56-789

    i could use C functions but i dont want to do that
    and i could print them one char at a time in a for loop but i am wondering if there are c++ functions for that
    something like setprecision (though that is for numbers)
    u get the idea

    cheers

    If you don't wanna use sprintf, why not use the string class?
