Procedural Language

Question 1

What is Procedural Language used for?

Answer 1

wide range of softwaere development as its easy to implement.

not possible to solve all kinds of problems with it or may b eineffiencient

uses traditional data types such as integers and strings which are built into the language + provide data structures like dictionaries and arrays

Question 2

Procedural Language (Mark Scheme)

Answer 2

• High-level, 3rd generation, imperative languages.
• Use sequence, selection and iteration.
• Program gives a series of instructions in a logical order line by line to state what to do and how to do it.
• Program statements are in blocks called procedures and functions.
• Break the solution down into subroutines which are rebuilt and combined to form a program.
• Statements are in a specific order i.e. sets tasks to be completed in a specific way.
• Logic of program is given as a series of procedure calls.

Examples include: VB.NET and Python.

Question 3

What data types does Procedural Languages use?

Answer 3

integers, strings

built into the language and provide data structures like dictionaries and arrays

Question 4

What is Structured Programming?

Answer 4

popular subsection of procedural programming in which control flow is given by 4 main programming structures

sequence - code executed line by line

selection - certain block of code is run if a specific condition is met using IF statements

iteration - block of code executed a certain number of times or while condition is met. FOR, WHILE, or REPEAT UNTIL loops

Recursion - fucntions are expressed in terms of themselves
function are executed, callining themselves, until condition known as base case (which doesn’t call function) is met

Question 5

What types of problems is Procedural programming for?

Answer 5

problems that can be easily expressed as a series of instructions using sequence, selection, iteration, recursion
