How do I put a cout and a cin on the same line?

Question

I am trying to put a cout and a cin on the same line as so cout << "Person 1:" << cin >> int p1;. Does anybody know a way that I could do the same thing successfully?

I'm using C++ on repl.it if that helps

Answer 1

The code you showed will not work, because you can't pass a std::istream (like std::cin) to operator<< of a std::ostream (like std::cout). You need to separate the expressions, separating them by either:

• a semicolon (Live Demo):

  int p1;
  cout << "Person 1:";
  cin >> p1;
  

• the comma operator (Live Demo):

  int p1;
  cout << "Person 1:", cin >> p1;
  

Answer 2

You can write:

int p1 = (cin >> (cout << "Person 1: ", p1), p1);

This would be a terrible idea in terms of writing clear code, I'm mainly posting it in response to several others who said that it is not actually possible.
