Bit Operations using Macros

Code

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

// Define bitwise macros here
#define SET_BIT(reg, bit)     (reg = reg | (1 << (bit)))
#define CLEAR_BIT(reg, bit)   (reg = reg & ~(1 << (bit)))
#define TOGGLE_BIT(reg, bit)  (reg = reg ^(1 << (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;
}
