An array is a collective name given to a group of similar quantities. These similar quantities could be percentage marks of 100 students, or salaries of 300 employee or ages of 50 employees. Thus an array is a collection of similar elements. These similar elements could be all ints, or all floats or all chars etc. usually, the array of characters is called a ?string?, where as an array of ints or floats is called simply an array. All elements of any given array must be of the same type i.e we can?t have an array of 10 numbers, of which 5 are ints
C permits nesting of two functions freely. There is no limit how deeply functions can be nested. Suppose a function a can call function b and function b can call function c and so on. Consider the following program:
During looping a set of statements are executed until some conditions for termination of the loop is encountered. A program loop therefore consists of two segments one known as body of the loop and other is the control statement. The control statement tests certain conditions and then directs the repeated execution of the statements contained in the body of the loop
An object, such as a CD Player, a printer, a car, etc, is built from assembling various parts. In the same way, C++ allows you to group various variables and create a new object called a class.
