What are Pascal data types?
What are Pascal data types?
There are four simple scalar data types in Pascal: INTEGER, REAL, CHAR and BOOLEAN. Arithmetic operators+,-,* are defmed for real and integers data types, with the division operators MOD, DIV (integer division) and I (real division).
What is Subrange data type?
A subrange type defines a subset of the values of a particular type. By using subrange types, you can easily detect errors occuring due to unreasonable values of a variable which shouldn’t take values outside a given boundary. Subrange types can be defined of type character, integer, in no case real!
What is type declaration in Pascal?
Type declaration indicates the category or class of the types such as integer, real, etc., whereas the variable specification indicates the type of values a variable may take. You can compare type declaration in Pascal with typedef in C.
What are enumeration and subrange types?
The enumerated type creates a new type that is unrelated to any other type, while the subrange type creates a new type that has a subset of the values of another existing ordinal type.
Which is the sub types of unstructured types of Pascal data types?
Data types can be categorized as scalar, pointer and structured data types. Examples of scalar data types are integer, real, Boolean, character, subrange and enumerated. Structured data types are made of the scalar types; for example, arrays, records, files and sets.

What are the different types of data types in Pascal?
Pascal – Data Types. Data types can be categorized as scalar, pointer and structured data types. Examples of scalar data types are integer, real, Boolean, character, subrange and enumerated. Structured data types are made of the scalar types; for example, arrays, records, files and sets. We will discuss the pointer data types later.
What is a subrange type?

What is the syntax of type declaration in Object Pascal?
Syntax of type declaration is − For example, the following declaration defines the variables days and age as integer type, yes and true as Boolean type, name and city as string type, fees and expenses as real type. Following table gives you details about standard integer types with its storage sizes and value ranges used in Object Pascal −
What is the use of constants in Pascal?
Use of constants makes a program more readable and helps to keep special quantities at one place in the beginning of the program. Pascal allows numerical, logical, string and character constants. Constants can be declared in the declaration part of the program by specifying the const declaration.
