Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    uint8_t count = 0;
    uint16_t output = 0;
    if(val != 0)
    {
        for(uint8_t i=0;i<8;++i)
        {
            uint8_t bit = (val >> i) & 0x1;
            output |= (bit<<(i*2));
        }
    }
    return output;
}

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

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