Bit Spreading Interleave Bits with Zeros

Code

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

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

    for (int i = 0; i < 8; i++)
    {
        if ((val >> i) & 1)          // is bit i = 1?
        {
            result |= (1 << (2*i));  // put it at position 2*i
        }}
    return result ;}


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

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