Bit Spreading Interleave Bits with Zeros

Code

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

#define BIT8_size   (8)

uint16_t spread_bits(uint8_t val) {
    // Your logic here
    uint16_t ret_val = 0;

    for(uint8_t bit_pos = 0; bit_pos < BIT8_size; bit_pos++){
        ret_val |= (((val >> bit_pos) & 1U) << (bit_pos * 2));
    }
    return ret_val;
}

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

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