int firstClass;

int economy;

public:

//Constructor

Plane()

{

firstClass=0;

//reserves one seat in first class

void resrFirsClass()

{

}

//reserves one seat in Economy class

void resrEconomy()

{

economy++;

}

//returns number of first class seats resreved

int getFirstClass()

{

return firstClass;

}

//returns number of economy seats reserved

int getEconomy()

{

}

//Makes Checkin process

void CheckIn()

{
