    fgets(string1, sizeof(string1), stdin);//fgets is used to count length of string even including space.stdin is used to read data from the user through the command-line or terminal.fgets is used to read a line of text (including spaces) from stdin and stores it as a string. It reads until it encounters a newline character (\n) or reaches the specified maximum length.
