Is the Bit Set

Code

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

uint8_t is_bit_set(uint8_t reg, uint8_t pos) {
    if(reg&(1<<pos))
    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;
}

Solving Approach

if(reg&(1<<pos);

here & operator compares each digit if same position 1 otherwise 0

return 1;

else 

return 0;
