Which Is the Type of Structure Type of Pascal Data Type?

When working with Pascal, it is important to understand the different data types that can be used. Data types play a crucial role in determining the structure and behavior of variables in a program. In Pascal, there are several types of data structures that can be used, each with its own unique characteristics and purposes.

Structured Types

Pascal provides several structured types that allow you to group related data together.


Arrays are one of the most commonly used structured types in Pascal. They allow you to store multiple values of the same type under a single identifier.

Arrays can be one-dimensional or multi-dimensional, depending on your needs. To declare an array, you need to specify its size and the type of elements it will hold.


Records are another important structured type in Pascal. They allow you to define a custom data structure by combining different types of fields.

Each field within a record can have its own data type. Records are especially useful when dealing with complex data structures that require multiple pieces of information.

Non-structured Types

Pascal also provides non-structured or simple data types that are not composed of multiple elements.

Numerical Types

Pascal supports various numerical types such as integer, real, and double. These data types are used to represent whole numbers, decimal numbers, and double-precision floating-point numbers respectively.

Character Types

In Pascal, characters can be represented using the char data type. This allows you to store individual characters like ‘a’, ‘b’, or ‘c’.

Boolean Type

The boolean data type is used to represent logical values. It can have two possible values: true or false. Booleans are often used in conditional statements and loop structures.

Type Conversion and Compatibility

Pascal provides a mechanism for converting between different data types. This is known as typecasting.

Typecasting allows you to convert a value of one data type to another compatible data type. However, it is important to note that not all types can be converted to each other, and care must be taken to ensure compatibility.


In Pascal, the choice of data type depends on the kind of information you want to store and manipulate. Whether you need a structured type like an array or record, or a simple type like an integer or boolean, Pascal provides a wide range of options to suit your needs. Understanding the different data types available will enable you to write more efficient and organized code.
