Bit Spreading Interleave Bits with Zeros

Code

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

//function prototype
uint8_t check_if_nth_bit_is_set(uint8_t reg, uint8_t n);
uint16_t spread_bits(uint8_t val);


uint16_t spread_bits(uint8_t val) {
    // Your logic here
    uint16_t result = 0;    
    for(uint8_t i = 0; i<8;i++)
    {
        result |= ((check_if_nth_bit_is_set(val,i)) << (i*2));
    }
    return result;
}

uint8_t check_if_nth_bit_is_set(uint8_t reg, uint8_t n)
{
    if (reg & (1 << n)) return 1;
    
    return 0;
}

int main() {
    uint8_t val;
    scanf("%hhu", &val);

    uint16_t result = spread_bits(val);
    printf("%u", result);
    return 0;
}
