Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
   uint16_t result = 0;
    for (int i = 0; i < 8; i++) 
    {
        uint8_t bit = (val >> i) & 1;           
        result |= (bit << (2 * i));             
    }
    return result;
}

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

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