Los objetos globales std::cout y std::wcout salida de control a un búfer de la secuencia de aplicación definido por el tipo (derivado de std::streambuf), asociada con el flujo de salida estándar C stdout .

Original:

The global objects std::cout and std::wcout control output to a stream buffer of implementation-defined type (derived from std::streambuf), associated with the standard C output stream stdout.

Estos objetos están garantizados para ser construido antes de la primera constructor de un objeto estático se llama y que están garantizados para sobrevivir a la última destructor de un objeto estático, por lo que siempre es posible escribir en std::cout en código de usuario .

Original:

These objects are guaranteed to be constructed before the first constructor of a static object is called and they are guaranteed to outlive the last destructor of a static object, so that it is always possible to write to std::cout in user code.

A menos que sync_with_stdio(false) se ha emitido, se puede acceder a estos objetos simultáneamente desde varios subprocesos, tanto para la salida con formato y sin formato .

Original:

Unless sync_with_stdio(false) has been issued, it is safe to concurrently access these objects from multiple threads for both formatted and unformatted output.

Una vez inicializado, std::cout es lazo () 'd a std::cin y se std::wcout lazo ()' d a std::wcin, lo que significa que cualquier operación de entrada en std::cin ejecuta std::cout.flush() (a través del constructor std::basic_istream::sentry) .

Original:

Once initialized, std::cout is tie()'d to std::cin and std::wcout is tie()'d to std::wcin, meaning that any input operation on std::cin executes std::cout.flush() (via std::basic_istream::sentry's constructor).

Una vez inicializado, std::cout también se atan () 'd a std::cerr y std::wcout es lazo ()' d a std::wcerr,, lo que significa que cualquier operación de salida en std::cerr ejecuta std::cout.flush() (a través del constructor std::basic_ostream::sentry) (ya que C + +11)

Original:

Once initialized, std::cout is also tie()'d to std::cerr and std::wcout is tie()'d to std::wcerr,, meaning that any output operation on std::cerr executes std::cout.flush() (via std::basic_ostream::sentry's constructor) (ya que C + +11)

Ejemplo

#include <iostream>
struct Foo {
    int n;
    Foo() {
       std::cout << "static constructor\n";
    }
    ~Foo() {
       std::cout << "static destructor\n";
    }
};
Foo f; // static object
int main()
{
    std::cout << "main function\n";
}

Output:

static constructor
