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++ Inline Function Example

C++ Inline Function Example

✅ C++ Program to Demonstrate Inline Function


#include <iostream>
using namespace std;

inline int add(int a, int b)
{
    return a + b;
}

int main()
{
    int x, y;
    cout << "Enter any two numbers:" << endl;
    cin >> x >> y;
    cout << "The sum of two numbers is:" << add(x, y) << endl;
    return 0;
}

📘 Explanation:

This program demonstrates the use of an inline function in C++. An inline function is a function that is expanded in line when it is called, instead of performing a normal function call.

The function add() is declared using the inline keyword. When this function is called inside main(), the compiler replaces the function call with the actual function code.

Inline functions are generally used for small functions to reduce the overhead of function calls and improve execution speed.

🧾 Sample Output:

Enter any two numbers:
5 7
The sum of two numbers is:12
