    cout<<"Count : "<<Count<<endl;
    }
};
 
int test:: Count;
 
int main(){
test t1,t2; //!when 1st obj. created static Count=0
t1.set_code();//!t1=1,count=1
test::show_Count();//!because Static function
t2.set_code();  //!t2=2,count=2
test::show_Count();//!count=2
test t3;//!count=2
t3.set_code();//!t3=3,count=3
test::show_Count();//!count=3
 
t1.show_code();
t2.show_code();
t3.show_code();
 
return 0;
