It's a question related to C++, but it's hard, so I'm leaving it "T"

I might be wrong because I'm just getting started, but I think it's relatively easy.

Which preprocessor indicator is required to use the command of an output stream object named std::cout?

I think I'm talking about iostream.

Which command (or reserved word) allows std:: to be omitted?

using namesapce std;

What does std mean?

standard

What is the name of the function that all c++ programs have?

main()

What symbol is the main body surrounded by?

int main(void) { }

So I think it's {}..

What is the operation indicator for using the std::cout output stream?

<<

Write a c++ program that prints your name on the console window.

#include <iostream>
using namespace std;
int main(void)
{
    cout<<"your name";
    return 0;
}

Write a c++ program that prints your first and last names in the console window, but let your first and last names appear in one line and then the next.

#include <iostream>
using namespace std;
int main(void)
{
    cout<<"your first name";
    cout<<endl;
    cout<<"your last name";
    cout<<endl; // a new line to look clean
    return 0;
}

That's it. These are very basic questions, so it's not that difficult. Please understand while looking for the textbook.
