Bit Operations using Macros

Code

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

// Define bitwise macros here

#define SET_BIT(r,b) ((r) |= (1<<b));
#define CLR_BIT(r,b) ((r) &= ~(1<<b));
#define TOG_BIT(r,b) ((r) ^= (1<<b));



uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    SET_BIT (reg,2);
    SET_BIT (reg,7);
     CLR_BIT (reg,3); 
    TOG_BIT (reg,5);
    return reg;
}

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