Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    // Your logic here
    uint16_t my_bits = 0x00;
    uint8_t bits_val[8];
    uint8_t bits_my_bits[16] = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};
    for(uint8_t i=0; i<8; i++){
        bits_val[i] = (val>>i)&(1);
    }
    for(uint8_t i=0; i<8; i++){
        bits_my_bits[2*i] = bits_val[i];   
    }
    for(uint8_t i=0; i<16; i++){
        if(bits_my_bits[i]==1){
            my_bits |= (1<<i);
        }
    }
    return my_bits;
}

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

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