Set or Clear a Specific Bit in a Register

Code

#include <stdio.h>

unsigned char modifyBit(unsigned char reg, int pos, int mode) {
    // Write your code here
    if(mode==1){
        reg|=(1<<pos);

    }
    else{
        reg&=~(1<<pos);
    }
    return reg;

}

int main() {
    unsigned char reg;
    int pos, mode;
    scanf("%hhu %d %d", &reg, &pos, &mode);
    printf("%d", modifyBit(reg, pos, mode));
    return 0;
}

Solving Approach

after entering reg,pos and mode in printf function call is happened then in function call i used fucntion call.Now if mode==1 then i will set else clear.
