Bit Operations using Macros

Code

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

// Define bitwise macros here
#define set 0b10000100 //OR
#define mask_toggle 0b00100000 //xor
#define clear_bit 0b11110111  //and

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    //set bit2 and 7;
    reg=(reg|set);
    reg=(reg&clear_bit);
    reg=(mask_toggle^reg);

    return reg;
}

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