What are the different ways to instantiate objects in C++?
In C++, objects can be instantiated in several ways.
- Use the default constructor.
- Create an object of the class named ClassName and assign it to a variable called objectName.
- Using a parameterized constructor:
- Create an object named objectName of class ClassName with the specified parameters.
- Using a copy constructor:
- Create an object, objectName, of class ClassName using anotherObject as the initial value.
- Allocate memory dynamically using the new operator and call the constructor.
- Create a new object of class ClassName and assign it to the objectName variable using the new keyword.
- After using the object, it is necessary to manually release the memory.
- Remove the object named objectName.
- Instantiate objects using an array:
- 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.
