This value is used in the malloc statement at line 10. It sets the buffer size as an argument based on the size of a character variable. Pointer character variable name is declared at line eight. And the result of the malloc function is saved in that pointer, which is immediately tested for the null pointer, which is something I hope you didn't forget. If the pointer is null, the program displays a message and quits. Otherwise, the printf statement at line 17 prompts for input, and the fgets function at line 18 reads that input.
