Write a C++ program to count the number of persons inside a bank, by increasing count whenever a person enters a bank, using an increment(++) operator overloading function, and decrease the count whenever a person leaves the bank using a decrement(--) operator overloading function inside a class.

Implementation of the above problem:

#include<iostream.h>

#include<conio.h>

class counter

{

int count;

public:

counter()

{

count=0;

}

counter operator++(int)

{

count++;

}

int get_count()

{

return count;

}

counter operator--(int)

{

count--;

}

};

void main()

{

clrscr();

counter c1;

cout<<"Initial No Of People "<<c1.get_count()<<endl;

c1++;

c1++;

c1++;

cout<<"Present No Of People "<<c1.get_count()<<endl;

c1--;

c1--;

cout<<"Present No Of People "<<c1.get_count()<<endl;

getch();

}

Thanks
