Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    uint16_t bit_spread = 0;
    int j=0;
    for(int i=0;i<16;i+=2)
    {
        uint16_t extract = (val >>j) & 1;
        bit_spread |= extract << i;
        j++;
    }
    return bit_spread;
}

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

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