Linux C/C++ 模板：用template消除歧义

一、代码

#include <iostream>using namespace std;//使用template消除歧义class Array{public:        template <typename T>        class InArray        {        public:                typedef T ElemT;        };};template <typename T>void output(T& arr){        //        //T::InArray<int>::ElemT num;        typename T::template InArray<int>::ElemT num;        num = 5;        cout<<"num is "<<num<<endl;}int main(int argc, char*argv[]){        Array arr;        output(arr);        return 0;}

二、输出结果
