Basic OOP Tutorial : C++ Programming | Object Oriented

Basic Programming Tutorial for C++

I found this in my old storage and I would like to share this to you. Here is an example of how to do a simple and basic object oriented programming in C++. Please be guided accordingly and follow the important points used in the objected oriented programming source code for C++. You could also customize your own file name, variables, method names and etc. Be playful and explore as possible.

Output:

Employee Information

Name:
Age:
Weight:
Height:
Salary:

Input:

• Name (string)
• Age (int)
• Weight (int)
• Height (double)
• Salary (double)

Note: You can also customize your own variables

Object Oriented Programming (OOP)

Your customized header file:

#include “Employee.h”

Note:

initialize class Employee first before using the methods created > Employee e;

Process that You Should Remember:

1. Include your header at the top (for the .cpp file)
2. Initialize the variables
3. Initialize the class you created (in .h file)
4. Set up Input
5. Call all set methods to set the values of the specific variables in the header
6. Print all or call the print method to view the employee information

Main File (.cpp)

//--www.skellainnovations.com--//

#include<iostream>
#include<conio.h>
#include "Employee.h"
using namespace std;
main ()
{
     string n;
     int a, w;
     double h, s;
     Employee e;
     cout<<"Enter Name: "; cin>>n;
     cout<<"Enter Age: "; cin>>a;
     cout<<"Enter Weight: "; cin>>w;
     cout<<"Enter Height: "; cin>>h;
     cout<<"Enter Salary: "; cin>>s;
     e.setName(n);
     e.setAge(a);
     e.setWeight(w);
     e.setHeight(h);
     e.setSalary(s);
     e.print();
     getch();
}

Header File:

(Employee.h) will serve as your customized library

Private:

all variables

Public:

all methods

Methods:

• void print();
• void setName(string n);
• void setAge(int a);
• void setWeight(int w);
• void setHeight(double h);
• void setSalary(double s);
• string getName();
• int getAge();
• int getWeight();
• double getHeight();
• double getSalary();

Constructors:

• Employee();
• Employee(string n, int a, int w, double h, double s);
