Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    uint16_t ret = 0x0;
    int i = 0;
    while (val > 0)
    {
        if (val & 0x1)
        {
            ret |= (1 << (2 *i));
        }
        val >>= 1;
        ++i;
    }
    return ret;
}

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

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