Where in the source code should I create an object?

Question

I want to create an object from a class that I have created. What I have been trying is to create the object (which can be testingclass) from a method of another class, which I will call classexample, but it says that testingclass is undeclared, which I assumed meant that it was out of the scope of the method, and the method couldn't access it. My program doesn't have a main function like in c or anything so I don't really understand where to put code that involves different objects if it can't go in methods.

Answer 1

Do you have the header file of the testingclass and did you import it to the file that create that object? That's all I can guess for your problems with very little information for very strange problem.
