Bit Operations using Macros

Code

#include <stdio.h>
#include <stdint.h>
#define set reg|1<<2;
#define set1 reg|1<<7;
#define clear reg&~(1<<3);
#define toggle reg^1<<5;

// Define bitwise macros here

uint8_t modify_register(uint8_t reg){
    reg=set;
    reg=set1;
    reg=clear;
    reg=toggle;
    return reg;
}

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