Bit Operations using Macros

Code

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

// Define bitwise macros here
#define SET_BIT(variable, position) ((variable) |= (1U << (position)));
#define CLEAR_BIT(variable, position) ((variable) &= ~(1U << (position)))
#define TOGGLE_BIT(variable, position) ((variable) ^= (1U << (position)))


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;
}
