Question 3
#include<iostream>
using namespace std;
class Test
{
public:
Test();
};
Test::Test() {
cout<<"Constructor Called \n";
}
int main()
{
cout<<"Start \n";
Test t1();
cout<<"End \n";
return 0;
}
Run on IDE
Output:
Start
End
Note that the line “Test t1();” is not a constructor call. Compiler
considers this line as declaration of function t1 that doesn’t recieve any
parameter and returns object of type Test.
