To understand the concept of Polymorphism in CPP, we will recommend you to visit here:Function Overriding, where we have explained it from scratch. Code: #include <iostream> using namespace std; //defining the class Addition to overload the method sumOf() to explain the concept of Polymorphi...
C++ - Initialization of Array of Objects C++ - Object as an Argument C++ - Empty Class C++ - Size of a Class C++ - Array of Objects Initialization With Constructors C++ - Typedef a Class C++ - Mutable Data Member C++ - Self-referential Class C++ - Polymorphism C++ - Cascaded Function ...
Elements in an array can be accessed randomly using indices.C17#include <stdio.h> int main() { int my_array[5]; int my_array_b[] = {0,1,2,3,4}; // You can init the array from it's elements. Size can be detected automatically here. size_t len = sizeof(my_array) / size...
Example of cascaded function call in C++ Consider the program: #include <iostream>usingnamespacestd;classDemo{public:Demo FUN1() { cout<<"\nFUN1 CALLED"<<endl;return*this; } Demo FUN2() { cout<<"\nFUN2 CALLED"<<endl;return*this; } Demo FUN3() { cout<<"\nFUN3 CALLED"<<endl;...

A string is an array of characters. C++ supports string types natively, but in C, a string is an array of char data, terminated with the '\0' character.C17#include <stdio.h> int main() { char* greeting_c = "Hello"; return 0; }...
When programming in R, logical values are commonly used to test a condition, which is in turn used to decide which branch from a complex program we should take. We will look at examples for this type of behavior in a later section in this chapter:x <- TRUE...
