Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
        // uint8_t n= sizeof(val);
         uint16_t result = 0;
         for(int i=7;i>=0;i--){
         uint16_t temp = ((val>>i)&1);
         result = (result << 2) | temp;
         }
    return result;
}

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

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