STL learning notes (3) function templates

Function templates cannot be partially customized

The Type compiler of function template parameters can be inferred and omitted, but the return value type must be written.

# Include <iostream> # include <typeinfo> using namespace STD; Template <typename T> class type {public: static string name () {return typeid (t ). name () ;}}; template <> class type <char >{public: static string name () {return "char ";}}; template <> class type <bool> {public: static string name () {return "bool" ;}}; template <> class type <double> {public: static string name () {return "double" ;}}; template <> class type <int> {public: static string name () {return "int ";}}; template <typename T> class type <t *> {public: static string name () {return type <t >:: name () + "Pointer ";}}; // function template <typename T> string type (t) {return type <t>: Name ();} int main () {// function template advantages: cout <type (123) <Endl; cout <type (45.6) <Endl; cout <type () <Endl; cout <"-------------------------" <Endl; int A = 10; char B = 'K'; cout <type (A * 1.0) <Endl; cout <type (a <B) <Endl; cout <type (& A) <Endl ;}
