You're almost there.
//begin
#include <iostream>
int main()
{
std::cout << "Welcome to C++!\n";
return 0;
}
//end
or
//begin
#include <iostream>
using namespace std;
int main
{
cout << "Welcome to C++!\n";
return 0;
}
//end
will work, but since this is a C++ program, you need to call the compiler as `c++ welcome.C` or `g++ welcome.C`.
