Bit Operations using Macros

Code

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

// Define bitwise macros here
#define BIT2 (1<<2) 
#define BIT3 (1<<3)
#define BIT5 (1<<5)
#define BIT7 (1<<7)

#define SETB(reg,x) (reg)|=(1<<(x))
#define CLRB(reg,x) (reg)&=~(1<<(x))
#define TOGB(reg,x) (reg)^=(1<<(x))
uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    SETB(reg,2);
    SETB(reg,7);
    CLRB(reg,3);
    TOGB(reg,5);
    return reg;
}

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