C++ Can someone explain this c++ program to me?

[Dhyana]

#include <iostream>

using namespace std;

class test{
public:
test(int data):mData(data)
{
std::cout<<"Const"<<std::endl;
}
~test()
{
std::cout<<"Const"<<std::endl;
}
int get(){
return this->mData;
}
private:

int mData;
};
int main()
{
// Write C++ code here
{
test t(5);
test* obj=new test(7);
cout<<"data: "<<t.get();
cout<<"data: "<<obj->get();
}
delete obj;
return 0;
}

#include <iostream>

using namespace std;

class test

Include is for using library files etc., iostream allows you to use standard input/output. The second line allows for abbreviated standard input/output, "class test" creates a data type named "test". I haven't studied c++ in a while, but it would probably help to mention where you got this from.
