C Program to Solve Two Sum Using Brute Force (With Algorithm & Output)

 Introduction The Two Sum problem is a popular coding interview question where we must find two indices of an array whose values add up to a given target. This program demonstrates a simple brute-force solution in C using nested loops and dynamic memory allocation. Problem Statement Given an integer array and a target value, return the indices of the two numbers such that they add up to the target. Each input has exactly one solution, and the same element cannot be used twice. The result should return the indices, not the values. If no solution exists, return NULL.  Algorithm / Logic Explanation Start the program. Traverse the array using a loop from index 0 to numsSize - 1 . Inside this loop, use another loop starting from i + 1 to numsSize - 1 . For every pair (i, j) , check if nums[i] + nums[j] == target . If condition becomes true: Allocate memory for 2 integers using malloc() . Store indices i and j . Set returnSize = 2 . Return the result poi...

C++ Program for Function Overloading Using Multiplication

C++ Program for Function Overloading Using Multiplication

✅ C++ Program to Demonstrate Function Overloading Using Multiplication

#include <iostream>
using namespace std;

class maths
{
public:
    int multiply(int a, int b)
    {
        return a * b;
    }

    double multiply(double a, double b, double c)
    {
        return a * b * c;
    }
};

int main()
{
    maths m;
    int a, b;
    double x, y, z;

    cout << "Enter any two integer numbers:" << endl;
    cin >> a >> b;

    cout << "Enter any three decimal numbers:" << endl;
    cin >> x >> y >> z;

    cout << "Multiplication of two numbers: "
         << m.multiply(a, b) << endl;

    cout << "Multiplication of three numbers: "
         << m.multiply(x, y, z) << endl;

    return 0;
}

📘 Explanation:

This program demonstrates function overloading in C++ using different data types. Function overloading allows multiple functions to have the same name but different parameter lists.

  • multiply(int a, int b) — multiplies two integer values.
  • multiply(double a, double b, double c) — multiplies three double values.

The compiler automatically selects the correct function based on the number and type of arguments passed during function call. This is an example of compile-time polymorphism.

🧾 Sample Output:

Enter any two integer numbers:
4 5
Enter any three decimal numbers:
1.2 2.0 3.5
Multiplication of two numbers: 20
Multiplication of three numbers: 8.4
