Bit Operations using Macros

Code

#include <stdio.h>
#include <stdint.h>

// Define bitwise macros here
 #define modify_register(reg)\
 ( ((reg) |  (1 << 2) | (1 << 7)) & ~(1 << 3) ) ^ (1 << 5)



int main() {
    uint8_t reg;
    scanf("%hhu", &reg);
    printf("%u", modify_register(reg));
    return 0;
}
