A multidimensional array is an array containing two, three, four, five, or more arrays. The increasing number of dimensions, increases the code complexity for the developers. The most popular arrays are single, two and three dimensional arrays. Two dimensional Arrays: A two-dimensional array can be defined as an array of arrays that needs two indices … Read more
Arguments are the variables, inside the parentheses, after the function name which is used to pass informations to functions. Beside passing variables and pointers, arrays can also be passed as a function parameter or argument. Syntax: Return_type functionName (Data_type array Name[]) { code to be executed; } Example: #include <iostream.h> using namespace std; … Read more
An array is a single variable which can store multiple values at a time. Thus, CPP array is used to hold many values under a single name. These values can be accessed then by referring to their index number. There are mainly two types of arrays: 1D array and multidimensional array. Syntax: data_type arrayName [arraySize]; … Read more

The storage classes in CPP are discussed below: Storage Classes Storage Place Default Value Scope Life-time Features auto RAM Garbage Local Within function Default storage class. extern RAM 0 Global Till the end of main program Visible to all the … Read more
When a function calls itself within its function block, it is called as self calling by a function. This whole process of self calling by a function is often termed as Recursion. Recursion is used to create a loop like behavior using a function and without using loop statements. Syntax: Return_type function_Name(parameters) { code to … Read more
Calling a function in CPP and passing values to that function can be done in two ways: Call by Value Call by Reference Call by Value Call by Reference Original value of the function parameter is not modified. Original value of the function parameter is modified. In this method, we pass a copy of … Read more
A function is a piece of code that can be used repeatedly in a CPP program. A function is mainly of two types: Built in Functions; which are already defined in CPP Library. User Defined Functions; which are created and defined by users. Syntax: Return_type functionName(parameters) { code to be executed; } … Read more
