用C++解决On an 8×8 grid of dots, a word consisting of lowercase Latin letters is written vertically in one column, from top to bottom. What is it? Input The input consists of multiple test cases. The first line of the input contains a single integer t (1≤t≤1000 ) — the number of test cases. Each test case consists of 8 lines, each containing 8 characters. Each character in the grid is either . (representing a dot) or a lowercase Latin letter (a –z ). The word lies entirely in a single column and is continuous from the beginning to the ending (without gaps). See the sample input for better understanding. Output For each test case, output a single line containing the word made up of lowercase Latin letters (a –z ) that is written vertically in one column from top to bottom. Example inputCopy 5 ........ ........ ........ ........ ...i.... ........ ........ ........ ........ .l...... .o...... .s...... .t...... ........ ........ ........ ........ ........ ........ ........ ......t. ......h. ......e. ........ ........ ........ ........ ........ .......g .......a .......m .......e a....... a....... a....... a....... a....... a....... a....... a....... outputCopy i lost the game aaaaaaaa

class Program { static void Main(string[ ] args) { Person David = new Person(); Person Alice = new Person(); // Initialize David David.age = 21; David.name = "David"; David.weight = 185.4; David.height = 72.3; // Initialize Alice Alice.age = 18; Alice.name = "Alice"; Alice.weight = 125.7; Alice.height = 67.1; // print some values Console.WriteLine("David’s age = {0}; David’s weight = {1}",David.age, David.weight); Console.WriteLine("Alice’s age = {0}; Alice’s weight = {1}", Alice.age, Alice.weight); } } Add this code to Program.cs. Compile and run it. Modify this code to print all of the instance variables of David and Alice. Run and understand the code. Add comments to record your understanding. Encapsulation in C#: In the previous example, we accessed the characteristics of the Person Class directly because the attributes (e.g. name, age, etc.) are defined as ‘public’. This is not a good practice and actually should be avoided in order to have ‘encapsulation’ – one of three most important features of object oriented design. The better option and practice is to define the attributes ‘private’ and then design some public methods to access them, normally ‘getXXX’ and ‘setXXX’. Amend the codes above accordingly. (Task 1.2)

You have been asked to develop an application, which would create a student id for a new student using their name, age and year of enrolment. The application should ask the user to enter their name, age and the year of enrolment and then formulate the new student id beginning with the first and last letter of their name followed by the year of enrolment and finally two random digits between 0 to 9. For example, if a user enters John, 19, 2023 then the id number might be Jn19202347 where 4 and 7 are random numbers generated by the application. When one new student number has been printed, the app should ask the user would they like to create another, if the user answers yes, then the app should run again. • The application code should be suitably formatted and indented, appropriately commented to show your understanding, error free and should give appropriate output (30 marks) • The application should make use of instantiable classes. The instantiable class should contain appropriately declared data members, a suitable constructor, all necessary set and get methods and a suitable method to create the id number. The main class should declare all necessary variables and invoke all of the necessary methods of the instantiable class during input, processing and output.
