First - Get a good text book on C++ and work through the examples in the book. Try Sams "Teach Yourself C++ in 24 Hours" by Liberty & Horvath or any similar book. The examples in textbooks are specifically designed to do what you want - practice problems for beginners. Work systematically chapter by chapter and don't be tempted to skip ahead. Learning is very important at the beginning so allow yourself enough time to understand as you progress. Unless you do this you will never be a good programmer.

Secondly - use Google to search for on-line courses in C++. These will also provide you with examples to use as practice.

Thirdly - search for C++ code examples to find out how other programmers use C++ to solve their problems. You can learn a lot from what other people have done.

Fourthly - set up a little project of your own - maybe a phone directory for your friends, a small database, a simple game (like Tic Tac Toe) or soemthing else that you would like to design. Start with a good modular design before you do any coding. Then code and test each function till you can put the whole project together and debug it until it works OK

Good luck!
