01_类模板的定义.cpp

#include<iostream>#include<vector>using namespace std;template<class T>class A{    public:    T t;    A(){}    A(const T &rt){ t = rt;}    ~A(){}};int main(){    vector<int> v;    A<double> a = 100.11;    cout<<a.t<<endl;}

2 sort.cpp

#include<iostream>#include<algorithm>using namespace std;int main(){    double m[]={45,76,54,45745,7,65};    for(auto k:m)        cout<<k<<" ";    cout<<endl;    sort(m,m+sizeof(m)/sizeof(m[0]));    cout<<"sorted:"<<endl;    for(auto k:m)        cout<<k<<" ";    cout<<endl;}
