    Need help.. beginner

    I have an array, and I malloc'd memory for it already, how do I set all the slots to spaces?
    Code:
    char **array;
    
    array = (char **) malloc blabla
    for(i = 0;loop){
    array[i] = (char *) malloc again..
    //HERE// array[i] = {ALL SPACES??}
    }

    Code:
    memset(memory, ' ', size)
    will fill size bytes of whatever is pointed to by memory with ' ', which is space.

    Compilers can produce warnings - make the compiler programmers happy: Use them!
    Please don't PM me for help - and no, I don't do help over instant messengers.
