Error No Matching Function For Call To ‘find

The compiler message is : no matching function for call to `Date::Date(int)' note candidates are: Date::Date(const Date&) note Date::Date(int, int, int) note Date::Date() Here is the the main file: /*-------------------- Lab7.cpp ------------------*/ #include

are special member functions used when an object is "constructed" (created). They have the same name as the class. The following code creates a class called A, then an object of that type. class A { public: int i; }; int main() { A http://www-h.eng.cam.ac.uk/help/tpl/languages/C++/constructors.html a; } There's no explicit function called A - when a is created, a constructor is used that the compiler has created. This time we'll create a constructor that, given an integer, sets the member variable i https://gcc.gnu.org/bugzilla/show_bug.cgi?id=40793 to that value. class A { public: int i; A(int x) { i=x;}; }; int main() { A a; } Though we don't use that constructor, the code doesn't compile, because as soon as you start error no writing your own constructors, none of the default constructors are created. The error message will be something like // error: no matching function for call to A::A() // note: candidates are: A::A(int) // note: A::A(const A&) (more about that final line later) In the following, a default value is defined for the constructor argument (i.e. if no value is supplied, 7 is used). Now compilation works. class A { public: int i; A(int error no matching x=7) { i=x;}; }; int main() { A a; } In the next example an argument is given when an object of type A is created, so that's ok too. class A { public: int i; A(int x) { i=x;}; }; int main() { A a(1); } The next example has an explicit constructor for when no parameter is given, and another constructor for when a single integer parameter is given. The programmer's trying to create a with one parameter, and b using no parameters. class A { public: int i; A() {}; A(int x) { i=x;}; }; int main() { A a(1); A b(); } The code compiles, but doesn't do what the programmer intended. Adding b.i=0; exposes the problem - there's a compilation error. To run the constructor with no parameters, A b; is needed. A b(); is a prototype for a function b that returns an object of type A. Copy constructor There's another type of constructor - it's called a copy constructor. It's used when an object is created by a copy being taken of an existing variable. class A { public: int i; A(const A&){}; // Copy constructor }; int main() { A a; A b=a; } But the code doesn't compile - copying works, but a itself isn't created.

Description Jonathan Schmidt-Dominé 2009-07-17 22:09:02 UTC When a function-templates gets wrong arguments there's an error "no matching function for call to result fun(args)". But the template-arguments aren't displayed. So it takes hours to search the reason for this error in some cases. The output should look like: "no matching function for call to result fun
