2)classA { A(); }one has been defined. Now look for it's declaration. (Should have been linked,) or does something else magical happen at compile time? @Cubbi: Thanks, I see how it sees both as default constructors, but why? I didn't know the compiler looks for class member dec...
for const object, it should return a const char reference or we simple return a char reference regardless? here is the example, below is the definition of MyString class. /** * file * MyString.h * * this header is the demonstrate the use of user defined constructor and overload operato...
Overloading is the creation of more than one procedure, instance constructor, or property in a class with the same name but different argument types. Overloading Usage Overloading is especially useful when your object model dictates that you employ identical names for procedures that operate on ...
C/C++是区分大小写的。构造函数的名字必须和类名完全一致。你的类叫Student，大写S；构造函数叫student，小写s，这就错了。编译器会认为student(...)不是构造函数，只是一个普通的成员函数。student(int n,string nam,char s)-〉Student(int n,string nam,char s)

Delegating constructors will be great but why not take this a step further and actually autogenerate the overloads when default parameters are used?This could apply to both constructors and other functions. The above example could simply be written as follows:public ref class Vector sealed { ...
