Answer 1

And
for(int j=i-1; i<0 ; j--)
i<0 never, true because you are staring from i=2
if it j<0,then if once, then always true, infinite loop. Because you are decreasing j, not I.
Check one by one condition...

OK. I already added code in your last question..

static bool isPrime(int x)
{
for( int i=2; i<=x/2; i++)
if(x%i== 0)
return false;
return true;
}
