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
    reg=reg|(1<<2);
    reg=reg|(1<<7);
    reg=reg&~(1<<3);
    if(reg&(1<<5))
    {
        reg=reg&~(1<<5);
    }
    else
    {
        reg=reg|(1<<5);
    }

        return reg;
}

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