In this above example, we have created the structure of Box type in which we have declared the length, breadth, height as its data members, and then we have defined parameterized constructor in which there are three parameters of float type which is used to initialize data members of Box type structure.
#include Ĭout<<"Area of Box is "< We will understand this more using an example code here. initialize variables with the value given in parameter Accordingly, constructors don’t return any value. However, there is no return type for a constructors. Like functions, the constructors can also take parameters. StructName(datatype1 variable1, datatype2 variable2. In general, constructors are special functions which are defined within a class to initialize its instance variables. However, you can provide the same values also. It is generally used to initialize objects with the parameter value that is passed through it during object creation. Answer: The parameterized constructor is used to provide different values to the distinct objects.It has the same name as the structure name.It does not have a return type like any other function.Parameterized constructors contain one or more than one parameter to initialize the value of the object created. Parameterized constructor inside structure in C++Ĭonstructors are the most important feature of C++ that makes the initialization of structure convenient. In this tutorial, we will learn struct constructors with parameters in C++ and also learn how to define them inside the structure. We can create a parameterized constructor by simply adding parameters to it. The parameters of parameterized constructor help in initializing an object when it is created. Let us see how we can implement parameterized constructor inside the structure definition in C++. We can define different constructors like default constructor, parameterized constructors inside them. We can declare one or more data members and member functions(constructors and other functions) inside the structure definition. The struct keyword is used to define structure type user defined datatype and then the name of the structure. Unlike C, Structures in C++ can have Constructor. It contains variables of different datatype. In C++, it is a collection of data members and member functions inside a single unit.PARAMETERIZED CONSTRUCTOR CODE
