Can objects also be treated as variables in c++ and why?

Answer 1

Your question is unclear to me. Is it your homework? Could you provide some context and an example code?

Answer 2

If you try to change the value of testValue outside of main, you get the same error.

It doesn't matter if it is an integer or a Student variable.

Answer 3

I think this might help derive meaning from my question.

Classes are user defined data types which can just be liken to a variable declared with a primitive data type. The variable declared with a primitive data type can be made globally to be accessed by any function right,

So this is now my question,

If objects are instances of a class, can they also be treated as a variable ?
If they are then why can't they be accessed by any function when declared global.

From the example code below, I have an object from the student class but I can't access it in an function. Therefore based on this, I want to know if objects are also variables?

Example
#include <iostream>
using std::cout;

class Student{

int marks[ 10 ];
string name;
string subjects [ 10 ];

void Grade( );

} ;
int testValue = 6;

Student s1;
s1.name = " Abban Justice";

int main( ){

/* here the s1 object can't be accessed by main function but variable testValue can be accessed */

cout<<s1.name<<endl;
cout<<testValue;

return 0;
}

Okay thanks

Answer 5

You can access the objects like any other variable, the problem in your case would be that you are trying to access a private member.

Members of a class are private by default, you have to explicitly specify if you want them public.
