Therefore, "joy" is stored as the four characters j, o, y, and \0. The length of a string, as measured by strlen(), doesn't count the null character.

String constants can be used to initialize character arrays. In pre-ANSI C, only external and static arrays can be initialized, but ANSI C permits automatic arrays to be initialized, too. The array size should be at least one greater than the string length to accommodate the ...
