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 = reg[pos]; lol this doesnt work because its not verilog ...
        reg |= (1<< pos);
    }
    else {
        // reg[pos] == 0; 
        reg &= ~(1 << pos); // technically this is comparing the shifted value to the reg 
    }
    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;
}
