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 temp = (uint16_t)val;
    uint16_t reg = 0;
    int n = 7;

    for(n; n>=0;n--)
    {
        reg |= ((temp & (1<<n)) << (n));
        //printf ("%u\n",reg); //Just added here for debug
    }
    return reg;
}

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

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