Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    uint16_t out = 0;
     

    for(uint8_t i = 0; i<8;i++)
    {
        uint8_t b = (val >> i) & 1;
        out |= (b << (2 * i));        
    }
    return out;
}

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

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