An integer, plus 100 is a complete square number, plus 168 is a complete square number, what is the number?

Program analysis: Within 100,000 to judge, the number plus 100 after the root, and then the number plus 268 after the root, if the result of the root to meet the conditions, that is the result

#include <stdio.h>

#include <math.h>

int main ()

{

long int i,x,y;

for (i=1;i<=100000;i++)

{

X=SQRT (i+100);

Y=SQRT (i+268);

if (x*x==i+100&&y*y==i+268)

printf ("%ld ", i);

}

return 0;

}
