why we use friend function in c++
global friend function c++
mfc friend class
friend declaration declares a non-template function
c++ friend member function
c++ template friend function
c++ friend class
c++ friend method
Introduction. We are familiar in passing value/variable into function. Instead of passing a variable, we pass a type (such as int , double , and Point ) into template. Passing type is known as generic programming, as we can program in generic type and invoke the code using a specific type. The goal of generic programming is

The following code builds fine on gcc. I added a definition of B::add(T) , as it was missing. It's very possible that the absence caused your link - not compilation! - error. template class B; template class A { private: T content; friend B; }; template class B
template class MyClass { T v; public: MyClass(T v):v(v){} templatevoid foo(MyClass obj) { std::cout << v << " "; std::cout << obj.v << " "; std::cout << v + obj.v << std::endl; } // Any other type of MyClass is a friend. template friend class MyClass; // You can also specialize the
Quite many C++ programmers, even those who are quite fluent at template programming, have the mistaken notion that template functions and classes can only be defined, not declared. In other words template T min(T v1, T v2) { return v1 < v2 ? v1 : v2; } class A { template friend class B; };.
This is the list of names “reserved to the implementation" that have been claimed by certain compilers and system headers of interest, and should not be used in the library. It will grow, of course. We generally are interested in names that are not all-caps, except for those like "_T" For Solaris: _B _C _L _N _P _S _U _X _E1
Self-friendship seems logical, but how to achieve that? Following will simply not work: Hide Copy Code. template class Item { friend class Item; };. Since Item is a class template and not a regular class, therefore symbol Item is invalid in this context. GCC reports
cat extdef.h template T foo(T); % cat extdef.cc #include "extdef.h" int main() { foo(1); } % CC extdef.cc -template=extdef "extdef.cc", line 3: Error: main() already had a body defined. Solution: Declare the friend function or class in a scope outside the class before the class declaration that declares it a friend
In this case, every specialization of the template becomes a friend, whether it is implicitl](http://cdn08.dayviews.com/501/_u4/_u1/_u9/_u2/_u8/_u1/u4192812/90847_1520538580/Template_typename_t_friend_class_manual_http_ibi_cloudz_pw_download_file_template_typename_t_friend.jpg)
