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 Parameter Order

C++ Program for Function Overloading Using Parameter Order

✅ C++ Program to Demonstrate Function Overloading Using Different Parameter Order

#include <iostream>
using namespace std;

class maths
{
public:
    void display(int a, double b)
    {
        cout << "Integer is: " << a
             << " and Double is: " << b << endl;
    }

    void display(double b, int a)
    {
        cout << "Double is: " << b
             << " and Integer is: " << a << endl;
    }
};

int main()
{
    int a;
    double b;
    maths m;

    cout << "Enter integer and double:" << endl;
    cin >> a >> b;
    m.display(a, b);

    cout << "Enter double and integer:" << endl;
    cin >> b >> a;
    m.display(b, a);

    return 0;
}

📘 Explanation:

This program demonstrates function overloading in C++ using different order of parameters. Even though both functions have the same name display(), they are treated as different functions because the parameter sequence is different.

  • display(int a, double b) — displays an integer first and then a double.
  • display(double b, int a) — displays a double first and then an integer.

The compiler determines which function to call based on the order and type of arguments passed. This is an example of compile-time polymorphism.

🧾 Sample Output:

Enter integer and double:
10 5.5
Integer is: 10 and Double is: 5.5
Enter double and integer:
3.14 7
Double is: 3.14 and Integer is: 7
