Question

Say I have a class I defined called ‘MyClass’. My ‘main’ method takes as arguments a list of filenames. Each filename is a config file for MyClass, but the program user can have as many objects of MyClass as they want. If they type in, say, 2 filenames as arguments to my main method, I would like to have 2 objects.

If I knew the user was limited to 2 objects, I could just use:

MyClass myclass1;
MyClass myclass2;

However this wouldn’t work if the user had say inputted 3 or 4 filenames instead. Can anyone help me and suggest a method I could use to create a number of insantiations of a class depending on the number of arguments my program is given?

Thanks

You could use a std::vector of MyClass instances – then you could make as many or as few as you wanted.

Take a look at this tutorial, for example (one of many out there on the web), to get you started.
