Bit Operations using Macros

Code

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

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

uint8_t modify_register(uint8_t reg) {
   reg =  SET_BIT(reg,2 );
   reg = SET_BIT(reg,7);
   reg = CLEAR_BIT(reg , 3);
    reg = TOGGLE_BIT(reg , 5) ;
    return reg;
}

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