Problem Statement

Create class with private data members and public methods to access them. This teaches encapsulation principle.
Logic: Hide data, provide controlled access through methods

Input Format

No user input.
Values are set and accessed using class methods.

Output Format

Values of private data printed using public methods.

Constraints

• Data members must be private

• Access only through public methods

Concept Explanation

Encapsulation means hiding data inside a class and allowing access only through methods.
This protects data from direct and unsafe access

Step-by-Step Logic

1.Create a class.

2.Declare data members as private (for example int value).

3.Create a public setter method to assign value to the private member.

4.Create a public getter method to read the private member.

5.In main(), use setter to set the value.

6.Use getter to print the value.

Code Solution

This explanation is written for learning purposes and to help beginners understand the concept clearly.

Output Example

Input:

Set value = 100

Output:

Value = 100

Common Mistakes

- Misreading input/output format.
- Not handling constraints and edge cases.
- Off-by-one errors in loops.
- Forgetting to reset variables between test cases (if any).
