(C++) Instance

 

When you construct a variable of a certain data type, you are creating an instance (also: object) of that data type.

 

In the code below an int called 'x' is instanciated.

int main() {   int x = 0; }

 

 

 

 

 

Advice

 

• Use std::unique_ptr to refer to objects of polymorphic type [1]
• Use to refer to sharedobjects [2]
