Public Data Members
All variables of a class are known as "data members of a class" and the variables which are declared in the public section of a class are known as "public data members of a class".
Public data members can be accessed through object name directly outside of the class.
Example:
Here, we have a class named "Numbers" with two public data members a and b, we will provide the value to them inside the main() and access (print) them inside main() also.
Program:
#include <iostream>
using namespace std;
class Numbers
{
public:
int a;
int b;
};
//Main function
int main()
{
//declaring object to the class
Numbers Num;
//assign values to a and b
Num.a = 100;
Num.b = 200;
//print the values
cout<<"Value of Num.a: "<<Num.a<<endl;
cout<<"Value of Num.b: "<<Num.b<<endl;
return 0;
}
Output
Value of Num.a: 100
Value of Num.b: 200
