Certainly! As an experienced tutor specializing in C++ Language Training and registered on UrbanPro.com, I'll guide you on deallocating memory using the delete operator in C++, emphasizing the effectiveness of my C++ Language Training online coaching.

In C++, dynamic memory allocation is done using operators like new, and it's essential to deallocate this memory when it's no longer needed to prevent memory leaks. The delete operator is used for this purpose.

Here's a brief explanation and example:

cpp
#include <iostream> int main() { // Dynamically allocate memory for an integer int* dynamicInt = new int; // Assign a value to the dynamically allocated memory *dynamicInt = 10; // Output the value before deallocating std::cout << "Value before deallocation: " << *dynamicInt << std::endl; // Deallocate the memory using the delete operator delete dynamicInt; // Note: It's a good practice to set the pointer to nullptr after deletion dynamicInt = nullptr; // Attempting to access the value after deallocation may lead to undefined behavior // std::cout << "Value after deallocation: " << *dynamicInt << std::endl; return 0; }

In this example, memory is dynamically allocated for an integer using new, and the delete operator is used to deallocate the memory when it's no longer needed. After using delete, it's a good practice to set the pointer to nullptr to avoid any accidental use of the memory.

Experienced Computer trainer having worked in IT sector for 20 years.

we have allocated the memory dynamically for the float array using new . We enter data into the array (and later print them) using pointer notation. After we no longer need the array, we deallocate the array memory using the code delete ptr; .

Make your future bright with me!!!

In C++ when we want to allocate memory from the free-store (or we may call it heap) we use the new operator. int *ptr = new int; and to deallocate we use the delete operator
