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 reg = 0;

    for (int i = 0 ; i < 8 ; i ++){
        
        uint8_t temp ;
        temp = (val & 1) ;
        
        reg = reg | (temp << i*2) ;

        val >>= 1 ; 
    }

    return reg;
}

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

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