A typical mistake made by most beginning programming students. What's missing from the following program?

#include <iostream>
int main()
{
    std::cout << "Hello";
    std::cout << "World\n";
    return (0);
}

Source code

Hint 1: "Hello World" is two words. Only one word is printed.

Hint 2: The word that's printed is not a real word.

Hint 3: The program prints less than what the programmer wanted.

Hint 4: The program needs a ____________.

Answer: The program prints:

    HelloWorld

The problem is that the programmer didn't print a space between the words.
