Dynamic Memory Allocation in C++

Introduction

Hello Coders!

In this exploration, we’ll delve into the essential concept of allocating and deallocating memory at runtime, providing the tools to create more adaptive and resource-efficient programs.

Using new and delete for Dynamic Memory Management

Dynamic memory allocation in C++ allows you to create and manage memory at runtime using new and delete operators. This flexibility is essential for scenarios where the size of the data or the number of elements is not known at compile time.

Allocating and Deallocating Memory

Here’s a basic example demonstrating the use of new and delete:

#include
int main() {
    // Allocating memory for an integer
    int* dynamic

Int = new int;
    *dynamic

Int = 42;

    // Printing the value
    std::cout << "Dynamic Integer: " << *dynamic

Int << std::endl;

    // Deallocating memory
    delete dynamic

Int;

    return 0;
}

In this example, new int allocates memory for an integer, and `delete dynamic

Int` deallocates the memory. It’s crucial to free dynamically allocated memory to avoid memory leaks.

Exercise: Implement Dynamic Memory Allocation for a Custom Data Structure

Now, let’s implement dynamic memory allocation for a custom data structure.

Conclusion

Feel free to modify the program or experiment with different custom data structures. This exercise will enhance your understanding of dynamic memory allocation in C++. Our exploration of Dynamic Memory Allocation in C++ reveals a key aspect of programming that empowers you to manage memory dynamically, enhancing the adaptability and efficiency of your code.
