Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    uint16_t x= 0;
    for(int i=0;i< 8;i++){
        uint8_t y = (val>>i) & 0x01;
        x|= y <<(2*i);
    }


    //  for(int i=0;i<8;i++){
    //     if(val & (1<<i)){
    //         reg |=(1<<(i*2));
    //     }
    //     else
    //     {
    //         reg &= ~(1<<(i*2));
    //     }
    // }


    return x;
}

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

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