Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    uint16_t final_val = 0,temp = 0;
    for(int i=0;i<8;i++){
        temp = (val&0x01) << (2*i);
        final_val |= temp;
        val = val>>1;
    }
    return final_val;
}

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

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