Bit Spreading Interleave Bits with Zeros

Code

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

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

int main() {
    uint8_t val;
    scanf("%hhu", &val);
    printf("%u\n", spreadBits(val));
    return 0;
}
