Define a C++ Class in Code::Blocks IDE

Overview

This tutorial outlines the steps to define a C++ class. We will use Code::Blocks IDE on Windows operating system.

Define a C++ Class

We will define an Employee class with two private member variables:

name
salary

name member variable is the string data type. salary member variable is the double data type.

// C++ class Employee
class Employee
{
public:

 string getName()
 {
 return name; // return employees's name
 }

 double getSalary()
 {
 return salary; // return employees's name
 }

 void setName(string name)
 {
 this->name = name;// set employees's name
 }

 void setSalary(double salary)
 {
 this->salary = salary;// set employees's name
 }

private:
 string name;
 double salary;
};

Define a C++ Class CodeBlocks

We will now define the main routine. In the main, we will create an object of the class Employee. Set some values to the member variables: name and salary. We will set the values using the setter member functions.
We will output the values by invoking the getter member functions.

int main()
{
 //Declare an Employee object
 Employee emp;
 //Invoke Setters
 emp.setName("John");
 emp.setSalary(2500.0);
 // Output
 cout << "Employee Name=" << emp.getName() << endl;
 cout << "Employee Salary=" << emp.getSalary()<< endl;
 return 0;
} // end main

Build and Run the C++ project. We should get the output of the object.
