Bit Operations using Macros

Code

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

// Define bitwise macros here
#define setbit(word,bit) word|=1<<bit;
#define clearbit(word,bit) word&=~(1<<bit);
#define togglebit(word,bit) word^=(1<<bit);

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    reg=setbit(reg,2);
    reg=setbit(reg,7);
    reg=clearbit(reg,3);
    reg=togglebit(reg,5);
    return reg;
}

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