Pointers for Memory and Vector in C++

Overview

This project demonstrates how to use pointers for memory manipulation, dynamic memory allocation, and working with arrays in C++. It includes examples of:

• Pointer arithmetic
• Dynamic memory allocation (new and delete)
• Array manipulation using pointers

The program is modularized for better understanding and serves as a learning resource for developers exploring C++ pointers and memory management.

Features

Static Array Manipulation

• Initialize an array with user inputs using pointers.
• Display array values and their memory addresses.

Dynamic Memory Allocation

• Demonstrates the use of new and delete to allocate and deallocate memory dynamically.

Sum of Array Elements

• Calculate the sum of elements in an array using pointer arithmetic.

Modular Code

• Functions like initializeArray, displayArray, and dynamicMemoryExample separate the logic for easier understanding.

Requirements

• C++ Compiler (e.g., g++ for Linux/Ubuntu or MinGW for Windows).
• Basic knowledge of C++ programming, particularly pointers and arrays.

How to Compile and Run

Clone the Repository

git clone https://github.com/s-v7/Ponteiros_Em_C.git
cd Ponteiros_Em_C

Compile the Program

g++ pointers.cpp -o output

Run the Executable

./output

Sample Output

Initializing Array with User Input

Enter a value for position [0]: 5
Enter a value for position [1]: 10
Enter a value for position [2]: 15
...

Displaying Array Addresses and Values

Address: 0x7ffee3a8b8d0 -> Value: 5
Address: 0x7ffee3a8b8d4 -> Value: 10
Address: 0x7ffee3a8b8d8 -> Value: 15
...

Calculating Sum of Array Elements

Sum of array elements: 150

Demonstrating Dynamic Memory Allocation

Enter the size of the dynamic array: 5
Dynamic Array [0]: 0
Dynamic Array [1]: 2
Dynamic Array [2]: 4
Dynamic Array [3]: 6
Dynamic Array [4]: 8
Dynamic memory deallocated.
