Instatiation of an object

Question

class class_name{
access_specifier:
members
} object_name;

What's the purpose of the object_name? Does it have something to do with instatiation?

Answer 1

Hello Geral

The object instantiated right after definition makes the object global in program.!

eg. You have an object 'object_name' .
All public members of this object are accessible throughout the program. //In main function and in other user defined functions also..

But when you instantiate an object inside main its scope and lifetime is limited to main function only.

~ swim ~ agree with you!
But usually simple programs uses class definitions outside any functions.

What you are saying is absolutely correct.

I just tried to figure out what this question is about.

Thanks for clarifying this point
😊🙏

Answer 3

Let me rephrase it. What I'm asking is: Why should I call the object right after class the declaration?

usual implementation
class class_name {
access_specifier:
members;
}
int main (){
class_name a;
}

"unusual" implementation

class class_name {
access_specifier:
members;
} OBJECT_Name;

int main (){
class_name a;
}

¿any implementation or usage?

Ok

Answer 6

The purpose of an object name is to have a variable of a custom data type which is the class_name.

When creating a class called class_name, Bear in mind that you are creating a custom data type.

When you create an object_name, bear in mind that you are creating a variable name.

You can initialize it with a constructor.

franky
Thanks! The thing here was I couldn't grasp the instatiation right after the class declaration, not the purpose of an object itself.
