Bit Operations using Macros

Code

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

// Define bitwise macros here



#define SETBIT(x,pos1,pos2)       ((x)|=(1<<pos1)|(1<<pos2))
#define CLEARBIT(x,pos)               (x)&=(~(1<<pos))
#define TOGGLEBIT(x,pos)              (x)^=(1<<pos)


uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
 
    SETBIT(reg,2,7);
    CLEARBIT(reg,3);
    TOGGLEBIT(reg,5);

    return reg;
}

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