Specifying the maximum string length to scanf dynamically in C (like “%*s” in printf)

Question

I can specify the maximum amount of characters for scanf to read to a buffer using this technique:

char buffer[64];

/* Read one li         


        

Answer 1

Another option is to #define the length of the string:

#define STRING_MAX_LENGTH "%10s"

or

#define DOUBLE_LENGTH "%5f"
