a snippet of program, i can't find the error?

Question

this is the code:
#include
#include
int count=0;
class obj{
public :
obj();
~obj();
};
obj() {
++count;
cout< }
~obj(){
--count;cout< }
int main(){
obj A;

cout<<"begin block "< obj B;
cout<<"end block"<
return 0;
}
where is the error? can someone point it out for me?
your help will be greatly appreciated.
best regards.

Answer 1

The error is when you define the constructor obj() and destructor
~obj(). Since you are defining the constructor and desctructor outside the class declaration, you need to use scope resolution like shown below.Else you will get compile error.
obj::obj(){
++count;
cout< }

obj::~obj(){
--count;cout< }
