| + | Désormais, quand nous créons un buffer, nous pouvons spécifier la taille du buffer. | ||
| + | |||
| + | <code cpp> | ||
| + | buffer<int, 64> bufferOfIntegers; // buffer contenant 64 entiers. | ||
| + | buffer<char, 32> bufferOfChars; // buffer contenant 32 caractères. | ||
| + | buffer<float> bufferOfFloats; // buffer contenant 128 (la valeur par défaut) nombres à virgule flottante. | ||
| + | </code> | ||
