Class and Objects Example in C++

The program creates a class called "Example" with two private data members data1 (integer) and data2 (float) and two public member functions: functionint() that sets the value of data1 and outputs it, and functionfloat() that prompts the user to enter a value for data2 and returns it.

In the main() function, two objects of the Example class, o1 and o2, are created. The functionint() method of o1 is called to set the value of data1. The functionfloat() method of o2 is called to prompt the user to enter a value for data2 and assign it to a variable called secondDataOfObject2. The value of secondDataOfObject2 is then outputted. Overall, the program demonstrates how to create objects of a class and call their member functions to manipulate the data members.

Source Code

#include<iostream>
using namespace std;
class Example
{
   private:
      int data1;
      float data2;
   public:
      void functionint(int d)
      {
        data1=d;
        cout<<"\nNumber: "<<data1;
      }
      float functionfloat()
      {
        cout<<"\nEnter data: ";
        cin>>data2;
        return data2;
      }
};
int main()
{
    Example o1,o2;
    float secondDataOfObject2;
    o1.functionint(12);
    secondDataOfObject2=o2.functionfloat();
    cout<<"\nEntered value :"<<secondDataOfObject2;
    return 0;
}
