Merge Sort in C++

  Merge Sort in C++ Introduction Merge Sort is a popular sorting algorithm that follows the Divide and Conquer approach. It divides an array into smaller subarrays, recursively sorts those subarrays, and finally merges the sorted subarrays to produce a completely sorted array. In this tutorial, we will learn how to implement Merge Sort in C++ . The program divides the array into two halves using the mid index, recursively sorts both halves, and then combines them using the merge() function. Merge Sort has a time complexity of O(n log n) in the best, average, and worst cases.

C++ Function Overloading Example (Different Parameters)

C++ Function Overloading Example (Different Parameters)

✅ C++ Program: Function Overloading with Different Parameters

#include <iostream>
using namespace std;

class Math {
public:
    void add(int a, int b) {
        cout << "Sum of two ints: " << a + b << "\n";
    }

    void add(double a, double b) {
        cout << "Sum of two doubles: " << a + b << "\n";
    }

    void add(int a, int b, int c) {
        cout << "Sum of three ints: " << a + b + c << "\n";
    }
};

int main() {
    Math m;
    m.add(10, 20);        // calls add(int, int)
    m.add(5.5, 2.5);      // calls add(double, double)
    m.add(1, 2, 3);       // calls add(int, int, int)
}

📘 Explanation:

This program shows Function Overloading in C++. The same function name add() is used with:

  • add(int, int) → Adds two integers
  • add(double, double) → Adds two doubles
  • add(int, int, int) → Adds three integers
The compiler chooses the correct function based on argument type and count.

🧾 Sample Output:

Sum of two ints: 30
Sum of two doubles: 8
Sum of three ints: 6

🔑 Keywords:

C++ function overloading, add function in C++, compile-time polymorphism, OOP concepts, C++ examples

📌 Hashtags:

🔍 Search Description:

This C++ program demonstrates function overloading with different parameter lists (integers and doubles). Example of compile-time polymorphism with sample output.
