这是建立模板的固定形式，template即模板，class指类别，T是类别的统称，可以使用的数据类型有int、char，float，double等等。举个例子：template < typename T >T min( T a, T b ){return a > b ? b : a;}这个 max 函数就是一个模板函数，它可以传入一个 “类型”的参数，以便实现任意类型...
template<classT>T GetMax(T a,T b) {returna>b?a:b; } GetMax(1,2);//正确GetMax(int,int);//错误template<classT>classpclass { ... }; pclass p1<int>;//正确pclass p2<2>;//错误template<intn>classpclass { ... }; pclass p1<2>;//正确pclass p2<int>;//错误 模板类的使用...
template<class T> //template<typename T> 也可以T Add(T x, T y){return x + y;}int main(){int a = 10;int b = 11;double c = 1.1;double d = 2.2;Add(a, b); // 生成整形模板Add(c, d); //生成double模板Add(a, d); // 编译报错,因为a是int,b是double,只有一个模板T,编译...
