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 Convert Celsius to Fahrenheit Using Inline Function

C++ Inline Function – Celsius to Fahrenheit

C++ Program to Convert Celsius to Fahrenheit Using Inline Function


#include <iostream>
using namespace std;

inline float celsiusToFahrenheit(float c)
{
    return (c * 9 / 5) + 32;
}

int main()
{
    float c;
    cout << "Enter temperature in Celsius: ";
    cin >> c;

    cout << "Fahrenheit = " 
         << celsiusToFahrenheit(c);
    return 0;
}

📘 Explanation:

This C++ program converts temperature from Celsius to Fahrenheit using an inline function.

The inline function celsiusToFahrenheit() applies the formula:

Fahrenheit = (Celsius × 9 / 5) + 32

Since the function is small and frequently used, declaring it as inline can improve performance by reducing function call overhead.

🧾 Sample Output:

Enter temperature in Celsius:
25
Fahrenheit = 77
