Bit Operations using Macros

Code

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

// Define bitwise macros here
#define SETBITS(x) (x|=0b10000100)
#define CLRBITS(x) (x&=(~0b1000))
#define TGLBITS(x) (x^=(0b100000))



uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    SETBITS(reg);
    CLRBITS(reg);
    TGLBITS(reg);
    return reg;
}

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