This is a C++ program
Write the program in computer and copy and paste it here please so i can understand it better instead of a paper please this is C++
Using our discussion and example of \"Abstract\" classes, design a class called TestQuestions. The class should have one private member, an integer called \"points\", and a static integer field called runningscore. The class needs an abstract method(function) called gradeIt()., that takes a character argument and returns void.
Now, create SIX child classes, one True,one False, one A, one B, one C and one D. The \"points\" value should be added to a constructor for the child classes. Each of these has to define the gradeIt() mehtod in such a way that if the character argument is T,F,A,B,C and D respectively, add the \"points\" field value to the runningscore static field.
Hopefully you can see what is developing here
Finally, create an array of 10 TestQuestion\'s and assign a random mix of the 6 subclasses. Each question can be worth 10 points, so this is the value you will assign in the constructors.

Each question can be worth 10 points, so this is the value you will assign in the constructors. This is enough for this assignment, but we can develop this further later.Solution
