Bit Operations using Macros

Code

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

// Define bitwise macros here

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order

    //Set bit 2 and 7
    reg = (reg | (1 << 2)) | (reg | (1 << 7));

    //clear bit 3
    reg = (reg & ~(1 << 3));

    //toggle bit 5
    reg = (reg ^ (1 << 5));

    return reg;
}

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