42. Namespace Variables Functions

We have already declared a namespace MathOps with:

• A variable int x = 10;
• A function int square(int n) that returns n * n

Your task is to:

• Print the value of x
• Call square(x) and print the result

Example Output:

x=10 Square=100 

Why this output?
Because the variable x is accessed using MathOps::x, and the function is called using MathOps::square(10).

Question Significance
Demonstrates how to access variables and functions defined inside a namespace using the scope resolution operator.
