Different types of conversions for C + + template classes

Conversion between different types if it is generally cumbersome to implement in C, C + + provides a kind of thing called template class, which is very easy to use by using templates class conversion.

The code is as follows:

Change.h

1#include <iostream>2#include <sstream>3 4 namespaceUtils5 {6template<classOut_type,classIn_value>7     classcstringtemplate8     {9      Public:Ten         Virtual~cstringtemplate (void){} One         StaticOut_type Covert (ConstIn_value &invalue) A         { - StringStream _stream; -_stream <<Invalue; the Out_type _result; -_stream >>_result; -             return_result; -         } +  -     Private: +Cstringtemplate (void){} A  at     }; -}

Specific use:

Main.cpp

1#include <iostream>2#include"change.h"3 4 using namespacestd;5 using namespaceUtils;6 7 intMain ()8 {9     string_string ="12345";Ten     intA = cstringtemplate<int,string>:: Covert (_string);  Onecout<<a<<Endl; A  -     return 0; -}
