The terminating zero is not considered as a part of string. Dropping large blocks of data like arrays of strings or bitmaps or masks for images into the program space means that you have more SRAM space for your program to run in. Compare two strings with limited length. This page can be quickly reached from the link: Locate character in string.

For example, under IDE version 1. Appends src to string dst of size siz unlike strncatsiz is the full size of dstnot space left. Determine the length of a fixed-size string.

The Arduino has two kinds of memory space: Email Required, but never shown. In the case where the length of src is less than that of nthe remainder of dst will be padded with nulls.
