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
    int temp=0;
    if(mode==1)
    {
        temp=reg | (1<<pos);
        return temp;
    }
    else
      {
        temp=reg & (~(1<<pos));
        return temp;
    }
}

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