What are the different ways to instantiate objects in C++?

In C++, objects can be instantiated in several ways.

  1. Use the default constructor.
  2. Create an object of the class named ClassName and assign it to a variable called objectName.
  3. Using a parameterized constructor:
  4. Create an object named objectName of class ClassName with the specified parameters.
  5. Using a copy constructor:
  6. Create an object, objectName, of class ClassName using anotherObject as the initial value.
  7. Allocate memory dynamically using the new operator and call the constructor.
  8. Create a new object of class ClassName and assign it to the objectName variable using the new keyword.
  9. After using the object, it is necessary to manually release the memory.
  10. Remove the object named objectName.
  11. Instantiate objects using an array:
  12. Create an array of objects with the specified class and size.

These methods can be chosen to instantiate objects according to specific needs and use cases.
