Bit Operations using Macros

Code

#include <stdio.h>
#include <stdint.h>
#define set1 1<<2
#define set2 1<<7
#define clr ~(1<<3)
#define tog 1<<5
// Define bitwise macros here

uint8_t modify_register(uint8_t reg) {
    reg|=set1;
    reg|=set2;
    reg&=clr;
    reg^=tog;
    return reg;
}

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