Explanation:
Destructor is a member function and it call automatically when the class object goes out of scope.
Out of scope means, the program exit, function end etc.

~xyz(){
print(destructor);
}
}
int main(){
xyz num;
}//end program
when the object is create the constructor will called and when the program end destructor will call automatically.
