Bit Operations using Macros

Code

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

// Define bitwise macros here
#define sbit(reg,x) reg |= 1<<x
#define cbit(reg,x) reg &= ~(1<<x)
#define tbit(reg,x) ((reg>>x) & 0x01)? cbit(reg,x) : sbit(reg,x)
uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    sbit(reg,2);
    sbit(reg,7);
    cbit(reg,3);
    tbit(reg,5);
    return reg;
}

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