Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {

    uint16_t result = 0;

    uint8_t shift = 7;

    for (int i = 7; i >= 0; --i) {
        result |= ((uint16_t)val & (1 << i)) << shift;
        shift--;
    }

    // printf("%016b\n%016b\n", val, result);

    return result;
}

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

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