Master C++ constructors with this comprehensive guide for beginners. Learn to initialize objects, set default values, and perform complex initialization tasks.
Constructor has the same name as the class name. It is case sensitive. Constructor does not have return type. We can overload constructor, it means we can create more than one constructor of class. We can use default argument in constructor. ...

Example: In the code below, variables i, j and k are all initialized to zero. C# Copy class A { void F() { int i = 0; int j = new int(); int k = default(int); } } end example Because every value type implicitly has a public parameterless instance constructor, it is not...
You can initialize any fields, or auto properties, in the body of the constructor. Beginning with C# 11, if you don't initialize all fields in a struct, the compiler adds code to the constructor that initializes those fields to the default value. A struct assigned to itsdefaultvalue is in...
A constructor without any arguments or with default values for every argument, is treated as default constructor. It will be called by the compiler when in need (precisely code will be generated for default constructor based on need).
You cannot declare a field, a property, an event, or the return type of a method as having an anonymous type. Similarly, you cannot declare a formal parameter of a method, property, constructor, or indexer as having an anonymous type. To pass an anonymous type, or a collection that cont...
