For Loop Expression Result Unused in xcode but code still works I don't want to show the whole loop i just need the last number it gets to what's wrong why the warning message ?

#include <stdio.h>

int main(int argc, const char * argv[])
{
// how much memory float consumes

printf("a float consumes %zu bytes\n\n", sizeof(float));

// what is the smallest number a short can hold and its largest

short x;
short y;

for (x; x > -1; x++) {
    continue;
}

for (y; y < 1; y--) {
    continue;
}

printf("\nSmallest short %d\nlargest short %d\n", x, y);

// same question but unsigned short instead

unsigned short i;

for (i; i < 1; i--) {
    continue;
}
printf("largest unsigned short is %d\n", i);

return 0;
}
