Weird error

[Your Computer]

The issue is that your for loop has a variable assignment for the second expression where it requires a boolean operator or something that returns true or false.

In other words, for (int i = 0; i = 10; ++i), the bold part is the problem. The assignment operator is not a boolean operator, so it doesn't return true or false. If you had < or <= instead of =, then it would work.
