Bit Operations using Macros

Code

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

// Define bitwise macros here

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    uint8_t pos1=2;
    uint8_t pos2=7;
    uint8_t pos3=3;
    uint8_t pos4=5;

    reg= reg|(1<<pos1);
    reg= reg|(1<<pos2);
    reg= reg&~(1<<pos3);
    reg= reg^(1<<pos4);
    


    return reg;
}

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