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
This paper first discusses static libraries, which are installed into a program executable before the program can be run. It then discusses shared libraries, which are loaded at program start-up and shared between programs. Finally, it discusses dynamically loaded (DL) libraries, which can be loaded and used at any time while a program is running. DL libraries aren't really a different kind of library format (both static and shared libraries can be used as DL libraries); instead, the difference is in how DL libraries are used by programmers. The HOWTO wraps up with a section with more examples and a section with references to other sources of information.
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.
A unique feature of c language is the preprocessor. A program can use the tools provided by preprocessor to make his program easy to read, modify, portable and more efficient.
