To access these memory locations programmers user pointers. The syntax for declaring a pointer is: Asterisk sign (*) represents the pointers. It is called the Deference operator. Here pointer_type is … Read more
C++ Structures store variables having different data types. For instance, n C++ programming language, user sometimes faces a situation where he needs to store a collection of various types of data in a single entity. Arrays provide the functionality to store data having same data types. Whereas for saving data of different data types, Structures … Read more

C++ arrays store one or more than one element. An array contains a number of items. A single variable is used to define an array of multiple items. Each item in an array is called an element. The image below shows an array that has 10 elements. Hence the length of array is 10. The … Read more
Loops Quite often there comes a situation when a programmer needs to repeat a piece of code multiple times. Why is Repetition Needed? Repetition provides following purposes: Duplication Taking input, sum, and average of multiple numbers using a limited number of variables For example, to add five numbers we may have two different algorithms: Declare … Read more
Constants C++ Constants are actually like fixed variables. Their value is declared in the beginning and cannot be altered afterward. In the C++ programming language, Constants are basically fixed values. These values are unchangeable throughout the program. These are also called Literals. C++ Constants Data types C++ constants have the same data types as C++ … Read more
For understanding the structure of the C++ code, first consider the following snapshot of the code. Output: Hello World The code consists of seven lines. Each line of the code is called statement of expression. Each C++ statement ends with semicolon(;). We explain each statement of the code. #include <iostream.h>; The first line is #include <iostream.h>;. … Read more
