Use of class templates

1. Format:template< template parameter table > (parameters can define default values directly)

Class name

{ ...};

Its member functions can be defined outside the class.

eg

1Template <classTNO,classTscore=int,intnum=Ten>2 classS3 {4 Private:5 TNO Sid[num];6  Public:7     intBel (Tscore ascore);8     voidsort ();9 };TenTemplate <classTNO,classTscore,intNum> One intS <TNO,TScore,num>:: Bel (Tscore ascore) A { -     return 0; - } theTemplate <classTNO,classTscore,intNum> - voidS <TNO,TScore,num>:: Sort () - { -     returnsid[0]; +}

2. The implementation of the Stack class template:

1#include <iostream>2 using namespacestd;3 4Template <classT>5 classStack6 {7 Private:8     intsize;9     inttop;Tent*space; One  Public: AStack (int=Ten); -~Stack () -     { the delete []space; -     } -     BOOLPushConstt&); - T pop (); +     BOOLIsEmpty ()Const -     { +         returntop==size; A     } at     BOOLIsfull ()Const -     { -         returntop==0; -     } - }; -Template <classT> inStack <t>::stack (intsize) - { to      This->size=size; +Space=NewT[size]; -top=size; the } *Template <classT> $ BOOLStack<t>::p Ush (Constt&Element)Panax Notoginseng { -     if(!isfull ()) the     { +space[--top]=element; A         return true; the     } +     return false; - } $Template <classT> $T stack<t>::p op () - { -     returnspace[top++]; the } - intMain ()Wuyi { thestack<Char> S1 (4); -S1.push ('x'); WuS1.push ('y'); -S1.push ('Z'); AboutS1.push ('u'); $S1.push ('v'); -      while(!S1. IsEmpty ()) -Cout<<s1.pop () <<Endl; -     return 0; A}
