Bit Operations using Macros

Code

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

#define SET_BIT(x,n) ((x) | 0x01 << n)
#define CLEAR_BIT(x,n) ((x)) & (~(0x01 << n))
#define TOGGLE_BIT(x,n) ((x)) ^ (0x01 << n);
// Define bitwise macros here

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;
}
