Thank you for help my task 1-5

Access control, constructor and destructor, and overloading Description Write and execute C++ programs for the following purposes: Access control for member variables and functions Utilize constructor and destructor Explore constructor overloading Utilize default argument Task 1 Access control Based on Lab5, change the structure to class and add control access to class. Step : create a new project Lab6_1, copy and change the files Lab5_2.h, Lab5_2.cpp, and Lab5 2 test.cpp to Lab6_1.h, Lab6_1.cpp, and Lab6_1 test.epp and import them to the project Step 2: in Lab6_1.h, change the structure to class, add key word public to the four member functions and keep these member variables as default private. Change the corresponding directives in this head file. Step3: in Lab6_1.cpp, you only need to change the include file to include the proper the header. Step 4: in Lab6_1_test.cpp, you only need to change the include file to include the proper the header. Step 5: compile the project and run and test the program. Extra tests: ETI: in Lab61 test.cpp, line 12: after "chk l.initialize"John Jone"):", try add a sentence "chk1.name and compile and see what is the error information. Explain the reason. Task 2 Constructor Based on Taskl, change to use a constructor instead of using member function initialize. Step : create a new project Lab6_2, copy and change the files Lab6_1.h, Lab6_1.cpp, and Lab6_1 test.cpp to Lab6_2.h, Lab6_2.cpp, and Lab6_2 test.cpp and import them to the project. Step 2: in Lab6_2.h, delete the declaration of initialize function, instead adding a constructor with an argument with type of string. Note that the constructor should not have return type and use std::string for the argument if you do not want to use namespace in the head file. Change the corresponding directives in this header file
