Bit Operations using Macros

Code

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

// Define bitwise macros here
#define setBit(reg,bit1,bit2)  reg =reg | ((1<<bit1) | (1<<bit2));
#define clearBit(reg,bit)      reg = reg & ~(1<<bit) ;
#define toogleBit(reg,bit)     reg = reg ^ (1<<bit);

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    setBit(reg,2,7);
    clearBit(reg,3) ;
    toogleBit(reg,5);

    return reg;
}

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