Bit Operations using Macros

Code

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

// Define bitwise macros here
#define setbit(bit,bitpos) bit|=1<<bitpos

#define clrbit(bit,bitpos) bit=bit&~(1<<bitpos)

#define togglebit(bit,bitpos) bit^=(1<<bitpos)

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    for(int i=0;i<8;i++)
    {
        if(i==2||i==7)
        {
            setbit(reg,i);
        }
        else if(i==3)
        {
            clrbit(reg,i);
        }
        else if(i==5)
        togglebit(reg,i);
    }
    return reg;
}

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