Now that I know some of the basics of C++, I must admit that I still find it very hard to deal with code that others have written in C++. This may inherently be so, as C++ allows for complex object hierarchies that are, or at least to me, very hard to grasp if one is just supplied with a C++ Project without any further comments or instructions.
So my question is more a question to the more experienced C++ programmers among you: how can someone understand a large C++ project written by others?
I easily loose my way and can be lost for weeks, if I try to understand how a large project of, for example, 10,000 lines of code is written. Functions of classes are pointers to functions of different classes that may or may not be overloaded and may or may not be inherited by other classes, etcetera, without ending.
Are there any practical tips that may speed up my ability to read and understand large C++ projects? Is there perhaps a tutorial with such tips? Please, elaborate! :)
