    "you need to store a 20-length string later on"

    that's why I said, "...unless you have a specific reason to do so..."

    In that case, yes - you would need to explicitly state the length as 21 in the definition.

    strcpy(str,"this a 20-char sting");
    The 1st parameter to strcpy just tells it where to start copying to; see strncpy if you want to limit the maximum number of characters to copy!
