Is the Bit Set

Code

#include <stdio.h>
#include <stdint.h>

uint8_t is_bit_set(uint8_t reg, uint8_t pos) 
{
    // Create a mask with only the bit at 'pos' set to 1
    uint8_t mask = (1 << pos);

    // Perform a bitwise AND operation
    // If the result is non-zero, the bit was set in reg
    if ((reg & mask) != 0) 
    {
        return 1;
    } 
    else 
    {
        return 0;
    }
}

int main() {
    uint8_t reg, pos;
    scanf("%hhu %hhu", &reg, &pos);
    printf("%u", is_bit_set(reg, pos));
    return 0;
}
