Bit Operations using Macros

Code

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

// Define bitwise macros here

uint8_t modify_register(uint8_t reg) {
    //clear bit 3,2,7
    reg &= ~((1<<2) | (1<<7) | (1<<3));
    //set bit 2,7
    reg |= ((1<<2) | (1<<7));
    //toggle bit 5
    reg ^= (1<<5);
    // Apply operations in order
    return reg;
}

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