TwoSum C Program

Overview

The TwoSum program is a simple yet efficient implementation of the classic Two Sum problem in C. It takes an array of integers and a target sum as input, then finds and returns the indices of the two numbers that add up to the target. If no such numbers exist, it informs the user accordingly.

Features

Dynamic Memory Allocation: Utilizes malloc to handle input sizes dynamically.
Input Validation: Ensures that user inputs are valid and handles errors gracefully.
Output: Provides clear feedback to the user about the results.

Getting Started

Prerequisites

A C compiler (like gcc) to compile the code.
Basic knowledge of C programming.

Installation

Clone the repository (or create a new file):

git clone https:/github.com/nerrison/TwoSum.git
cd TwoSum

Compile the code:
```
gcc -o TwoSum TwoSum.c
```
Run the program:
```
./TwoSum
```

Usage

The program will prompt you to enter the number of elements in the array.
Next, enter the elements of the array, one by one.
Finally, input the target sum.
The program will output the indices of the two numbers that add up to the target, or inform you if no such numbers exist.

Example

Enter the number of elements in the array:
5
Enter the elements of the array:
2
7
11
15
Enter the target number:
9
Indices of the numbers that sum to 9: 0 and 1

Code Structure

TwoSum Function: Contains the logic to find two indices.
Main Function: Handles user interaction and input validation.
