Make a list for yourself of precisely what is confusing about those topics, for example
Typecasting: Is it necessary to cast my variable when I am doing XYZ
Twos compliment: How do I handle negative numbers
etc.
Now you have a list of things you can search other sites for, like you can Google "C++ typecasting XYZ" or "2's compliment negative numbers". I know people on this site would be more than happy to help you with specific questions about specific areas, but you've got to figure out what those are.
