Constructor overloading is a concept of having more than one constructor with different parameters list, in such a way so that each constructor performs a different task. For e.g.Vectorclass has 4 types of constructors. If you do not want to specify the initial capacity and capacity incremen...
// overloading class constructors #include <iostream.h> Class CRectangle { int width, height; public: CRectangle (); CRectangle (int,int); int area (void) {return (width*height);} }; CRectangle::CRectangle () { width = 5; height = 5; } CRectangle::CRectangle (int a, int b)...
If you’re coming from a language such as Java or C#, the concept of constructor overloading is a pretty common one. But as a refresher in say C#, we can overload constructors like so : classMyClass{publicMyClass(string value){this.value=value;}publicMyClass(int value){this.value=va...

类Class(三):构造函数重载(Overloading constructors) 像其它函数一样,构造函数也可以重载,有相同的名字但有不同的参数:不同的参数个数或参数类型。编译器会根据参数自动匹配相应的函数,例如: #include <iostream>using namespacestd;classRectangle {intwidth, height;public:...

Unlike a semi-trailer, an overloaded Java method or constructor isn't necessarily a bad thing. Java allows overloading. It's a useful tool in the Java programmer's toolbox. In Java, the term overload means that there are multiple versions of a constructor or method. They will each have...
Overloading with the zero-argument constructor However, it might also be common in the application to create an origin point at coordinates (0,0). In this case, the developer might provide a zero-argument constructor that lets a developer create a point with 0, 0 as the defaults. ...
