C++ Program to Check Even or Odd Using Inline Function

#include <iostream>
using namespace std;

inline bool isEven(int n)
{
    return (n % 2 == 0);
}

int main()
{
    int n;
    cout << "Enter a number: ";
    cin >> n;

    if(isEven(n))
        cout << "Even number";
    else
        cout << "Odd number";

    return 0;
}
  

📘 Explanation:

This program demonstrates the use of an inline function in C++ to check whether a given number is even or odd.

The function isEven() is declared using the inline keyword. It returns true if the number is divisible by 2, otherwise it returns false.

Inline functions are preferred for small logical operations because they help reduce function call overhead and improve performance.

🧾 Sample Output:

Enter a number:
