    Sizing Memory Q.

    Suppose I declare a variable as:

    char Str[100];

    Does it make any difference which of the following I use for initializing the array?

    memset(Str, 0, sizeof(Str));


    memset(Str, 0, sizeof(char * 100));

    I have been using method number 1 a lot lately and didn't know if there was some down side that I'm just not aware of.

    The first is better for an array.
    p.s. What the alphabet would look like without q and r.

    >>char Str[100];
    >>for initializing the array
    char str[100] = {0};
    will initialise it all to 0
    When all else fails, read the instructions.
