Si NDEBUG se define como un nombre de macro en el punto en el código fuente <cassert> donde se incluye, a continuación, assert no hace nada .

Original:

If NDEBUG is defined as a macro name at the point in the source code where <cassert> is included, then assert does nothing.

Si NDEBUG no está definida, entonces los controles assert si su argumento (que debe tener un tipo escalar) compara igual a cero. Si lo hace, assert salidas de aplicación específica de la información de diagnóstico en la salida de error estándar y llama std::abort. La información de diagnóstico se requiere para incluir el texto de expression, así como los valores de las macros estándar __FILE__, __LINE__, y la __func__ variable estándar .

Original:

If NDEBUG is not defined, then assert checks if its argument (which must have scalar type) compares equal to zero. If it does, assert outputs implementation-specific diagnostic information on the standard error output and calls std::abort. The diagnostic information is required to include the text of expression, as well as the values of the standard macros __FILE__, __LINE__, and the standard variable __func__.

Ejemplo

#include <iostream>
// uncomment to disable assert()
// #define NDEBUG
#include <cassert>
 
int main()
{
    assert(2+2==4);
    std::cout << "Execution continues past the first assert\n";
    assert(2+2==5);
    std::cout << "Execution continues past the second assert\n";
}

Output:

Execution continues past the first assert
test: test.cc:8: int main(): Assertion `2+2==5' failed.
