Bit Operations using Macros

Code

#include <stdio.h>
#include <stdint.h>
#define SetBit(x,n) ((1U << n) | x)
#define ClearBit(x,n) ((x) & ~(1U << (n)))
#define ToggleBit(x,n) (x ^ (1U << (n)))

// Define bitwise macros here

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    reg = SetBit(reg,2);
    reg = SetBit(reg,7);
    reg = ClearBit(reg,3);
    reg = ToggleBit(reg,5);
    return reg;
}

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