Bit Operations using Macros

Code

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

// Define bitwise macros here
#define Set_bit(value,bit) (value |= (1U << bit))
#define Clear_bit(value,bit) (value &= ~(1U << bit))
#define Toggle_bit(value, bit) (value ^= 1U << bit)

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    Set_bit(reg, 2);
    Set_bit(reg, 7);
    Clear_bit(reg,3);
    Toggle_bit(reg,5);
    return reg;
}

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