Q6. What is ref and out

Ans.

ref and out are keywords in C# used for passing arguments to methods by reference.

ref keyword is used to pass arguments by reference, allowing the method to modify the value of the argument

Example: void UpdateValue(ref int num) { num = num * 2; }
Example: void GetValues(out int a, out int b) { a = 10; b = 20;
