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 to Check Even or Odd Using Inline Function

C++ Inline Function Example – Even or Odd

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


#include <iostream>
using namespace std;

inline bool isEven(int n)
{
    return (n % 2 == 0);
}

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

    if(isEven(n))
        cout << "Even number";
    else
        cout << "Odd number";

    return 0;
}

📘 Explanation:

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

The function isEven() is declared using the inline keyword. It returns true if the number is divisible by 2, otherwise it returns false.

Inline functions are preferred for small logical operations because they help reduce function call overhead and improve performance.

🧾 Sample Output:

Enter a number:
6
Even number
