    all i did was fix your include of iostream.h to iostream, and i changed the prototype and the function.

    Code:
    string mystring = "99999";
    char * mychararray;
    
    mychararray =  mystring.data();
    
    long mystring2numbers = atoi( mychararray );
    this should work if you can follow, there may be an easier way,
    i dont know for sure, havent done much work with this.

    if you are having a hard time following this, search on google
    for atoi and string.data

    what about the other way around?

    like

    int x = 4
    string y;

    make y = x

    Code:
    int mynumber = 4;
    char mychar = itoa(mynumber);
    string mystring = mychar;

    i believe thats correct

    ILoveVectors, your methods of converting are bad. The data() function doesn't necessarily return a null-terminated character array, and therefore will cause your code to not work as expected, and possibly crash. Use c_str() instead if you want to get to a character array. Or use a stringstream. Also, your second method uses the non-standard itoa function which usually returns a character array, not a single character. Even if it returned a single character, that's not very helpful for two digit numbers. Use a stringstream.

    See this FAQ (39.1 & 39.2) for stringstream examples, or for a simpler examples I believe there is a FAQ on this website.
