C# FINAL EXAM 2025 QUESTIONS AND
ANSWERS
When we call a constructor method among different constructors, we match the suitable
constructor by matching the name of constructor first, then the number and then the type of
parameters to decide which constructor is to be overloaded. What is this process called?
Inheritance
Encapsulation
Polymorphism
Method overriding - ANS Polymorphism
Which of the following statements are correct for the difference between value and reference
types? Each correct answer represents a complete solution. Choose all that apply.
Memory allocation in value type takes place during runtime which is same as that of reference
type.
Value types require garbage collector to release memory, but reference types don't.
Value types are stored on the stack, whereas reference types are stored on the heap.
Value types cannot contain null values, but reference types do. - ANS Value types are stored
on the stack, whereas reference types are stored on the heap
