Bit Operations using Macros

Code

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

// Define bitwise macros here

uint8_t modify_register(uint8_t reg) {
    uint8_t result1, result2, result3, result4;
    result1 = reg | (1 << 7);
    result2 = result1 | (1 << 2);
    result3 = result2 & (~(1 << 3));
    result4 = result3 ^ (1 << 5);
    // Apply operations in order
    return result4;
}

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