Bit Operations using Macros

Code

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

// Define bitwise macros here
#define SETB(x, p) ((x) | (1 << (p)))
#define CLRB(x, p) ((x) & ~(1 << (p)))
#define TOGB(x, p) ((x) ^ (1 << (p)))

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    return TOGB(CLRB(SETB(SETB(reg, 2), 7), 3), 5);
}

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