    specific length

    Hi, i was wondering how i could specify the length of something in a console program like:

    Code:
    #include <iostream.h>
    #include "apstring.h"
    
    int main()
    {
         apstring state;
    
         cout << Which state do you live in?
         cin >> state;
         cout state;
    }
    How would i make it so state was two letters as in AZ or CA?

    thanks!

    This person should get a cookie for using the code tags (joke from a friend)

    but back to the point....use chars.

    char[2];
    //insert code here.

    that should work (no need for code, ain't posting it)

    i believe getline would need 3 instead of 2, because it reserves a spot for the null character

    if you're working with state abbrev. you probably need a data table with state names to abbrev. the first two or three letters of any state should suffice. (except for mississippi and missouri.)
