At the core of a programming language are its data types and operators. These elements define the limits of a language and determine the kind of tasks to which it can be applied. As you might expect, C++ supports a rich assortment of both data types and operators, making it suitable for a wide range of programming. Data types and operators are a large subject. We will begin here with an examination of C++’s foundational data types and its most commonly used operators.

C defines several types of data and each type has unique characteristics. Because data types differ all variables must be declared prior to their use and a variable declaration always includes a type specifier. The compiler requires this information in order to generate correct code. In C there is no concept of a type-less variable. A second reason that data types are important to C programming is that several of the basic types are closely tied to the building blocks upon which the computer operates bytes and words. Thus C lets you operate on the same .
