C# Questions & Answers on Method with Parameters for Freshers

1. Which of these data types can be used for a method having a return statement in it?

a) void
b) int
c) float
d) all of the mentioned

Answer: d

2. What is the process of defining more than one method in a class differentiated by parameters known as?

a) Function overriding
b) Function overloading
c) Function doubling
d) None of the mentioned

Answer: b

Explanation: Function overloading is a process of defining more than one method in a class with same name differentiated by function signature i:e return type or parameters type and number. Example – int volume(int length, int width) & int volume(int length, int width, int height) can be used to calculate volume.

3. Which of these methods is executed first before execution of any other thing that takes place in a program?

a) main method
b) finalize method
c) static method
d) private method

Answer: c

Explanation: If a static method is present in the program then it will be executed first, then main will be executed.
