结果,在编译的时候,出现了如下错误提示: D:\mingw32\bin>gcc c:\cygwin\home\config3.cpp -o c:\test.exe c:\cygwin\home\config3.cpp:11:5: error: specializing member 'testclass<int>::_data' requires 'template<>' syntax c:\cygwin\home\config3.cpp:12:5: error: specializing member 'test...

The class templates define a family of classes in C++; the syntax for the class template is below. template <class Ttype> class ClassName { // class body; } Now let’s try an example using the class template. #include <iostream> using namespace std; template <typename Delftstack> ...
Once we've declared and defined a function template, we can call it in other functions or templates (such as themain()function) with the following syntax functionName<dataType>(parameter1, parameter2,...); For example, let us consider a template that adds two numbers: ...
template<int i = 3 > 4> // syntax error class X { /* ... */ }; template<int i = (3 > 4)> // OK class Y { /* ... */ };The template parameter lists of template template parameters can have their own default arguments, which are only in effect where the template template...
NOTE: Visual C++ 5.0 does not support this syntax currently. The above sample causes compiler error C1001. In this case the compiler would generate function Test(int). The compiler generates the definition using the template function Test. ...
Finding the template syntax in implementation code to be visually crowded, I decided to use #define to keep the code as clean and readable as possible. What do you think? Rectangle.cpp 1234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950...
