Bit Operations using Macros

Code

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

// Define bitwise macros here
#define SET_BIT(val, bit) ((val) | (1 << (bit)))
#define CLEAR_BIT(val, bit) ((val) &  (~(1 << (bit))))
#define TOGGLE_BIT(val, bit) ((val) ^ (1 << (bit)))
uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
  reg = SET_BIT(reg,2);
   reg =SET_BIT(reg,7);
   reg =CLEAR_BIT(reg,3);
   reg =TOGGLE_BIT(reg,5);
    return reg;
}

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