Format specifiers for uint8_t, uint16_t, …?

Question

If I have an integer variable I can use sscanf as shown below by using the format specifier %d.

sscanf (line, \"Value of integer: %d\\n\", &         


        

Answer 1

As others said, include <stdint.h> header that defines the format macros. In C++, however, define __STDC_FORMAT_MACROS prior to including it. From stdint.h:

/* The ISO C99 standard specifies that these macros must only be
   defined if explicitly requested.  */
#if !defined __cplusplus || defined __STDC_FORMAT_MACROS
