Please solve the following problem using C++ language. Please include comments so that I am able to understand the code and please follow the instructions shown. Thanks in advance.

// text.h

Test your implementation by activating LAB2_TEST1 (15 pts) Function prototype: Text toReverse(Text obi, int position) const 2. Implement the operators+-. Test it by activating LAB2-TEST2. (15 pts) Function prototype: Text operator += (const Text & input2); Notel: Make Source code with the test cases are provided (text,h and test2.cpp). Make sure you create corresponding methods in text.cpp as well. There were added the following two lines into the configuration file: ingrvale corespondnd n #define LAB2 TEST! #define LAB2 TEST2 0 // Programming recursion // Programming operation and recursion Plus, there are included test cases to test your implementation
