Diagram (and C++ Code) Explaining Classes, Objects, Variables and Methods Using Airplanes
Diagram (and C++ code) that explains how classes, objects, methods and variables work in object oriented programming using airplanes as a real world analogy. The class is called "Airplane" and the objects are different types of airplanes: Cessna Skyhawk, Gulfstream G150 and a Boeing 727. Variables: TopSpeed, Range Methods: TakeOff, Climb, Land
// Airplane class/object
// Matt R
// Used Code::Blocks IDE with GCC compiler
#include
#include
using namespace std;
class Airplane {
public:
int TopSpeed;
int Range;
string EngineType;
// Methods
void Takeoff() {
cout << "The Cessna Skyhawk is taking off from runway." << endl;
} // end method TakeOff
void Climb() {
cout << "The Cessna Skyhawk is climbing to 1,500 feet." << endl;
} // end Climb method
void Land() {
cout << "The Cessna Skyhawk is landing onto the runway." << endl;
} // end Land method
}; // end class Airplane
int main() {
// Create object of class Airplane
Airplane CessnaSkyhawk;
// Set variables
CessnaSkyhawk.TopSpeed = 142;
CessnaSkyhawk.Range = 640;
// Print out variables
cout << "The Cessna Skyhawk top speed is: " << CessnaSkyhawk.TopSpeed << endl;
cout << "The Cessna Skyhawk range is: " << CessnaSkyhawk.Range << endl;
// Call methods from class Airplane
CessnaSkyhawk.Takeoff();
CessnaSkyhawk.Climb();
CessnaSkyhawk.Land();
return 0;
} // end main function
Supplies
- C++ compiler like gcc.
- IDE like CodeBlocks
- Computer
