In the file 'data.txt', there is information about students - name, C++ score, and Java score. The number 12 in the first line indicates the number of students. (1) Create a dynamic array and store name, C++, and Java score. Visual representation of the data structure: ``` | name | name | ...... | name | | score | score | | score | | information | information | | information | ``` (2) After storing the name, C++ score, and Java score, calculate the average and store it in the array. (3) Complete the two classes and write the main function to print out the following result: ```cpp class Score { private: int cpp; int java; double average; public: // Complete the class } class Student { private: string name; Score* score; public: // Complete the class } ``` Contents of the file 'data.txt': ``` 12 Hailey 80 90 Paul 88 73 April 78 56 Sonya 80 71 John 56 68 Pam 70 72 Oliver 90 95 Eugene 67 79 Harry 81 65 Jessica 56 82 Eileen 98 77 Lily 77 72 ``` Expected program output: ``` Enter the fileName: data.txt Data from file --------------------------- Hailey 80 90 85 Paul 88 73 80.5 April 78 56 67 Sonya 80 71 75.5 John 56 68 62 Pam 70 72 71 Oliver 90 95 92.5 Eugene 67 79 73 Harry 81 65 73 Jessica 56 82 69 Eileen 98 77 87.5 Lily 77 72 74.5 ```
