Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    uint16_t result=0;
    uint16_t one_mask=1;
    uint16_t temp;
    for (int i = 0; i < 8; i++) {
        temp=(one_mask&(val>>i))<<2*i;
        result|=temp;
    } 
    return result;
}

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

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