Bit Operations using Macros

Code

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

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


uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    reg|=BIT2;
    reg|=BIT7;
    reg&=~(BIT3);
    reg^=BIT5;
    return reg;
}

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