Format specifier in scanf for bool datatype in C

Question

I am using bool datatype in C std99 whose definitions are defined in <stdbool.h>. Now I want the user to give me input. What format specifier I must use in scanf to input the boolean value of 1 byte from the user and then manipulate it afterwards in my program.

Answer 1

There is none.

Use a temp object as the size of _Bool is implementation dependent.

#include <stdbool.h> #include <stdio.h>  bool b; int temp;  scanf("%d", &temp); b = temp;
