Funksiya uchun shablon turi

Shablon sinflarini qо‘llanilishi shablon funksiyasini a’zosini ifodalaydi. Parametrlari shablon sinflarini ifodalovchi global shablon funksiyalar - algoritmlarini aniqlash mumkin. Masalan oddiy shablonni pufaksimon algoritm orqali tartiblashni shunday aniqlash mumkin.

template void bubble_sort(Vector& v)

{ unsigned n = v.size();

for (int i=0; i

for (int j=n-1; i

if (v[j] < v[j-1])

{ // v[j] va v[j-1] о‘rnini almashtiramiz

T temp = v[j];

v[j] = v[j-1];

v[j-1] = temp;

}

}

Vector tipini qismiga tenglik funksiyasini berish mumkin emas, balki unga ikkinchi parametr sort() funksiyasini berish kerak. Bu parametr obyekt sinfini ifodalaydi, qaysiki tenglik operatsiyasini qayta aniqlashda.
