Question
Which keyword is used to declare an object of a class in C++?
objectstructnewclass
Solution
In C++, the keyword used to declare an object of a class is new. This keyword is utilized for dynamic memory allocation, allowing you to create an instance of a class on the heap. However, you can also declare an object of a class on the stack simply by specifying the class name followed by the object name (e.g., ClassName objectName;), without the need for new.
To summarize:
- new: Used for dynamic allocation (
ClassName* objectName = new ClassName();). - ClassName objectName;: Used for stack allocation.
Thus, while "new" is correct for dynamic allocation, depending on the context, you may simply declare an object by using its class name.
