    concatenating characters not character strings?

    I have an array of characters (not a char string) and I would like to take certain elements

    example a[4] and a[13]

    and concatenate them together to use in an equality test such as ( == "JR")

    What is the simplest method to concatenate characters into a string to do this?

    strcat seems to work on strings not simple characters

    The easiest may well be to just compare the characters:
    Code:
    if (a[4] == 'J' && a[13] == 'R')
    If you really want to form a string out of them:
    Code:
    char sample[3] = "";
    sample[0] = a[4];
    sample[1] = a[13];
    if (strcmp(sample, "JR") == 0)
    Note that your '== "JR"' idea won't work because you'll end up comparing pointers rather than strings.
