Some syntax for C + + templates

The specificity of function templates

Template <class t>int Compare (T v1,t v2) {if (V1<V2) Return-1;else if (v1>v2) return 1;elsereturn 0;} Template <>int Compare<char *> (char * s1,char * s2) {    return strcmp (S1,S2);}

The specificity of class templates

Template <class t>class test{public:void operator () () {cout<< "test<t>" <<endl;}}; Template <>  class test<char>{public:void operator () () {cout<< "test<char>" <<endl;}};

the partial specificity of the template

Template <class t,class o>  struct testclass{testclass () {cout<< "I,o" <<endl;}}; Template <class t>struct testclass<t *,t *>{testclass () {cout<< "t*,t*" <<endl;}};

member Templates

Template <class t>class v{public:template <class t1>void Insert (int position, T1 T) {cout<< "insertion" <<endl;}};

Determine the current template parameters based on the previous template

Template <class T,class s=vector<t> >   class test{public:test () {cout<< "test" <<ENDL;} Private:s T; }

Binding of templates to friends

Template <class t>   class queue{friend bool operator = = <T> (const queue <T> &t1,const Queue < t> &t2) {cout<< "T,t" <<endl;return true;};

inline function templates

Inline template <typename t> t min (const t& a,const T & B) {return a<b?a:b;}

Note that the position of the inline and template is not interchangeable

Template internal specified type

Template <class t>class test{public:typename t::size_type T;   Template internal definition type};

Non-type template parameters

Template <class t,size_t n>void arr (T (&para) [N]) {int i=0;for (i=0;i<n;i++) cout<<para[i]<< Endl;};
