c# programming
Answer 1:
Output:
Explanation:
In the above program, we created a class Sample that contains data member emp_id, name, and salary. Here, we defined a parameterized constructor to initialize the data members, and we also defined a Print() method to print the values of data members.
Now look to the Program class, the Program class contains the Main() method, which is the entry program of the program. Here, we created an array of objects and initialized using default and parameterized constructor and print values of data members using the Print() method.
Answer 2:
Output:
Explanation:
The above program will generate syntax error because the public access modifier is not valid for destructors in C#.
Answer 3:
Output:
Explanation:
In the above program, we created a class Sample that contains data member emp_id, name, and salary. Here, we defined default and parameterized constructor to initialize the data members, and we also defined a Print() method to print the values of data members, and we defined a destructor that will call automatically we scope of the object get finished.
Now look to the Program class, the Program class contains the Main() method, which is the entry program of the program. Here, we created two objects of E1 and E2. Then we call the Print() method with E1 and E2. After that destructor called twice when the scope of E1 and E2 get finished.
Answer 4:
Output:
Explanation:
The above program will generate errors because delete is not a built-in keyword in C#. That's why the below statements will generate errors,
delete E1; delete E2;Answer 5:
Output:
Explanation:
In the above program, we created a class Sample that contains data member emp_id, name, and salary. Here, we defined default and parameterized constructor to initialize the data members, and we also defined a Print() method to print the values of data members, and we defined a destructor that will call automatically we scope of the object get finished.
Now look to the Program class, the Program class contains the Main() method, which is the entry program of the program. Here, we created an array of objects. Then we call Print() method with E[0] and E[1]. After that destructor called twice when the scope of E[0] and E[1] get finished.
