C++ Code explanation?
Here is a nest loop in some code. Any help with what it means exactly would be greatly appreciated.
for (i = 1; i <= numlocker; i++)
{
x = 0;
for (j = 1; j <= numlocker; j++)
{
if ( i % j == 0)
x++;
}
if ( x % 2 != 0) {
cout << "Locker " << i << " is open";
cout <<endl;
}
}

It appears to be a lock pick algorithm. It consists of a pair of nested loops. The lock code appears to be a pair of integers less than some number called "numlocker". The inner loop increments X until the first number is found. It then uses this number along with the second until both match the code which opens the lock. However, I've never seen the symbol "%" used in C++ except in formatting text. Perhaps the above is something known as pseudo code which isn't really a language but rather a blueprint of how the algorithm works.

You're missing the declaration and setting code for numlocker.
Right now that's a error numlocker is not defined.
