Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
 
    uint16_t result = 0;

    for ( int i = 0 ;  i < 15; i++ )
    {
        uint16_t bit=(val >> i ) & 1;
        result  |= (bit<< (i*2) );


    }
    return result;
}

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

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