Q1. What is the use of ref?
Ans. 
The 'ref' keyword in C# is used to pass arguments by reference instead of by value.
• Allows a method to modify the value of the argument passed to it

• Useful when you want to update the original value of a variable inside a method

• Can be used with value types and reference types

• Example: void UpdateValue(ref int num) { num = 10; }

• Example: int value = 5; UpdateValue(ref value); // value will be 10 after the method call
