Bit Operations using Macros

Code

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

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

Solving Approach

Each task was done sequentially. I forgot macros in my previous attempt ( I didn't read properly ;-;) so I added them.
