Bit Spreading Interleave Bits with Zeros

Code

#include <stdio.h>
#include <stdint.h>
uint16_t spread_bits(uint8_t val) {
   
    uint16_t result = 0;
    int i;
    for (i = 0; i < 8; i++) {
      
        if ((val >> i) & 1) {
            
            result |= (uint16_t)1 << (2 * i);
        }
    }

   
    return result;
}

int main() {
    uint8_t val;
    

    scanf("%hhu", &val);
    uint16_t result = spread_bits(val);
    printf("%u\n", result);
    
    return 0;
}
