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

    unsigned char result = 0;

    if( mode )
    {
        result =    reg | ( 1 << pos) ; 
    }
    else
    {
        result =    reg &  ( ~( 1 << pos) ) ; 
    }

    

    return result;
}

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