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. We will also take a closer look at variables and examine the expression....

This module returns to the topics of data types and operators. In addition to the data types that you have been using so far, C++ supports several others. Some of these consist of modifiers added to the types you already know about. Other data types include enumerations and typedefs. C++ also provides several additional operators that greatly expand the range of programming tasks to which C++ can be applied. These operators include the bitwise, shift, ?, and sizeof operators.

A variable declared with the const modifier cannot have its value changed during the execution of your program. Thus, a const “variable” isn’t really variable! You can give a variable declared as const an initial value, however. For example, const int max_users = 9; creates an int variable called max_users that contains the value 9. This variable can be used in expressions like any other variable, but its value cannot be modified by your program.

The data type of a variable is important because it determines the operations that are allowed and the range of values that can be stored. 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 “typeless” variable.

Historically, a course on data structures has been a mainstay of most computer science departments. Over the last 18 years, however, the focus of this course has broadened considerably. The topic of data structures has now been subsumed under the broader topic of abstract data types (ADTs)—the study of classes of objects whose logical behavior is defined by a set of values and a set of operations.

Data communications and networking are changing the way we do business and the way we live. Business decisions have to be made ever more quickly, and the decision makers require immediate access to accurate information. Why wait a week for that report from Germany to arrive by mail when it could appear almost instantaneously through computer networks? Businesses today rely on computer networks and internetworks.

The collection of builtin data types in a data base system (e.g. integer, floating point number, character string) and builtin operators (e.g. +, , *, /) were motivated by the needs of business data processing applications. However, in many engineering applications this collection of types is not appropriate. For example, in a geographic application a user typically wants points, lines, line groups and polygons as basic data types and operators which include intersection, distance and containment.

Follow this tip to learn how to use LiveCycle Designer to write data to and retrieve information from databases. Using these features, form designers can develop forms that allow users to blend manually entered information with enterprise data and display database record details in form fields based on selection criteria such as a key field. For example, people can use printable forms to view supplier details based on part numbers, or use an order form that populates fields such as color and size selectors based on model type.
