Pascal Interview Questions and Answers

• It is a structured language that has structures like repeat-until statements, if-else.
• It provides simplicity and a modern approach
• It includes data structures like arrays, pointers, records, and files
• It provides exact sizes used by operators

It is a collection of elements of the same type which allows defining the set data type.

A program consists of modules known as Pascal units which consist of code blocks, variables, statement procedures, and declarations.

Data types mean a range of value that a variable can store. The predefined data types are integers, the real numbers, Boolean data types files that define only two values, and the last one is a char data type.

To display the flow of control in a structured manner, Pascal uses a structured programming language. It also uses the goto statement that gives control to the main program in a recursive manner.

The sub-range means implementation of the functions for data conversions on the data types like real to the integer. One such is

• X: 1.. 10;
• Y: ‘a’..’z’;
• Z: Apple. Mango;

The different pointer types used in Pascal are recorder pointer, reference pointer, and the last associate pointer.

The first method is an application which allows using implementation and features according to the compiler and second is a compiler that is likely to implement the features that are compatible with one another.

Constant means which remains unchanged.

Following are the 6 constants

• Set Types
• Real Types
• Ordinal Types
• Pointer Types
• String and char

The syntax used to declare constant is
Identifier = constant_value;
