Pascal Data Types
Pascal is a programming language that supports various data types. Here are some commonly used data types in Pascal:
Integer: The
integer
data type is used to store whole numbers. It can represent both positive and negative numbers within a certain range. For example,x: integer;
.Real: The
real
data type is used to store floating-point numbers. It can represent decimal numbers with a fractional part. For example,y: real;
.Boolean: The
boolean
data type is used to store logical values. It can represent eithertrue
orfalse
. For example,isFound: boolean;
.Char: The
char
data type is used to store single characters. It can represent any character from the ASCII character set. For example,c: char;
.String: The
string
data type is used to store sequences of characters. It can represent a collection of characters of varying length. For example,name: string;
.Array: The
array
data type is used to store a collection of elements of the same data type. It can represent a fixed-size or dynamic-size collection. For example,numbers: array[1..10] of integer;
.Record: The
record
data type is used to define a custom data structure that can hold multiple fields of different data types. For example,
type
Person = record
name: string;
age: integer;
end;
- Pointer: The
pointer
data type is used to store memory addresses. It can be used to manipulate data indirectly. For example,p: ^integer;
.
These are just a few examples of data types in Pascal. Pascal also supports other data types, such as sets, enumerated types, and file types, which provide additional flexibility in programming.
