Strings in Pascal

In this article, Mytour will provide you with information about strings in Pascal, as well as the functions and procedures of strings in Pascal. Let's start by understanding strings in Pascal.

Strings in Pascal

Extended Pascal offers various string objects depending on the system and implementation.

You can define a string in several different ways:

-

Character Array: This is a string consisting of a sequence of characters with the same size enclosed in single quotes.
- String Variables: String variables, defined in Turbo Pascal.
- Short String: String variable with specific size.
- Null Terminated String: Variable of type pchar.
- AnsiStrings: AnsiStrings are strings of unlimited length.

Pascal only provides one string operator, which is the string concatenation operator (+).
