Class in c++

A pointer to a C++ class is done exactly the same way as a pointer to a structure and to access members of a pointer to a class you use the member access operator -> operator, just as you do with pointers to structures. Also as with all pointers, you must initialize the pointer before using it. Let us try the following example to understand …

In Programming, sometimes there is a need to perform some operation more than once or (say) n number of times. Loops come into use when we need to repeatedly execute a block of statements. For example: Suppose we want to print “Hello World” 10 times. This can be done in two ways as shown below:We cannot create objects of abstract classes. A pure virtual function (or abstract function) in C++ is a virtual function for which we can have an implementation, But we must override that function in the derived class, otherwise, the derived class will also become an abstract class.

C++.C++ strings are sequences of characters stored in a char array. Strings are used to store words and text. They are also used to store data, such as numbers and other types of information. Strings in C++ can be defined either using the std::string class or the C-style character arrays. 1.This line of code create a variable of type Display* and initializes it with the address of a newly created object. Display *disp; // (1) disp = new Display(); // (2) First line of code simply declares a variable of type Display*. Depending on your compiler settings - the pointer may or may not be initialized. A class defines a type of object, but it isn't an object itself. An object is a concrete entity based on a class, and is sometimes referred to as an instance of a class. Objects can be created by using the new keyword followed by the name of the class, like this: C#. Customer object1 = new Customer(); Classes are really the heart and soul of C++ -- they are so foundational that C++ was originally named “C with classes”!
