Bit Operations using Macros

Code

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

// Define bitwise macros here
#define SETBIT(reg, bit)  reg |= (1 << bit)
#define CLEARBIT(reg,bit) reg &= ~(1 << bit)
#define TOGGLEBIT(reg,bit) reg ^= (1 <<bit)
uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    SETBIT(reg, 2);
    SETBIT(reg, 7);
    CLEARBIT(reg, 3);
    TOGGLEBIT(reg,5);

    return reg;
}

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