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 – Even or Odd Number

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


#include <iostream>
using namespace std;

inline int even(int num)
{
    return (num % 2 == 0);
}

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

    if(even(n))
        cout << n << " is an Even number" << endl;
    else
        cout << n << " is an Odd number" << endl;

    return 0;
}

📘 Explanation:

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

The inline function even() checks if the number is divisible by 2. If the condition is true, the function returns 1 (true), otherwise it returns 0 (false).

Inline functions are commonly used for small and frequently called functions because they reduce function call overhead and improve performance.

🧾 Sample Output:

Enter the number:
8
8 is an Even number
