Set or Clear a Specific Bit in a Register

Code

#include <stdio.h>

int modifyBit(int reg, int pos, int mode) {
    int data = reg;
    if(mode==1){
        data |= (1<<pos);
    }
    else{
        data &= ~(1<<pos);
    }
    return data;

}

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