Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    int y = val<<7;
    int x = y&(1<<14);
    y = val<<6;
    int z = y&(1<<12);
    y = val<<5;
    int p = y&(1<<10);
    y = val<<4;
    int q = y&(1<<8);
    y = val<<3;
    int r = y&(1<<6);
    y = val<<2;
    int s = y&(1<<4);
    y = val<<1;
    int t = y&(1<<2);
    y = val<<0;
    int i = y&(1<<0);
    int m = i|t|s|r|p|q|z|x;

    return m;
}

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

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