Bit Operations using Macros

Code

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

// Define bitwise macros here
#define Set_Bit(r, b) ((r) |= (1 << (b)))
#define Clear_Bit(r, b) ((r) &= ~(1 << (b)))
#define Toggle_Bit(r, b) ((r) ^= (1 << (b)))

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    Set_Bit(reg, 2); // Set bit 2
    Set_Bit(reg, 7); // Set bit 7
    Clear_Bit(reg, 3); // Set bit 3
    Toggle_Bit(reg, 5); // Toggle bit 5
    return reg;
}

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