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
    reg |= (1U << 2) | (1U << 7);   // Set bits 2 and 7
reg &= ~(1U << 3);              // Clear bit 3
reg ^= (1U << 5);               // Toggle bit 5
    return reg;
}

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