c++ problem involving pointers and classes

Need done in less than an hour! Use the following code segment for your answers to the questions below: template< class T > class Mystery {   public:     private:        T *what1;        T *what2;        int size;  // The size is for the two arrays(what1 and what2). }; int main( ) {   const int SIZE = 5;    int grades1[ ] = { 100, 90, 87, 89, 60}; // LINE 1    int grades2[ ] = { 98,56,90,90,100}; //LINE 2    Mystery < int > object1( grades1, grades2, SIZE); // LINE 3    cout << object1[3] << endl; // LINE 4    return 0; } Questions: 1. The code on LINE 3 in the main is supposed to copy all array elements of grades to the *what that is used as an array.   ( 5 points) What is missing in the class Mystery? Come up with the implementation inside the class. 2. Come up with the implementation inside the class to make the code on LINE 4 work when executed in a complete program.  (3 points) 3. Where should you delete the pointers of the class?  Modify the class.  (2 points) 4.  What should be done to the main ( ) if the main contains the following statement below LINE4 ?   ( 2 points)    Mystery < double > object2( grades4, grades5, SIZE);
