Computer Science

a document that sets out the tests that will be carried out during testing

an error where the code has been structured incorrectly and the syntax rules haven’t been followed

an error where the program will run, but won’t do what the programmer expected

Programming project: selection II

Using selection when developing programs

Arithmetic operators

Relational operators

Logical operators

Nested selection

Good programming practices

Selection challenge

Programming project: selection I

In this unit pupils will explore the benefits of good programing practices and why subroutines are used in programs. They will create conditions in programs which use arithmetic, relational and logical expressions. They will develop their understanding of selection and explore nested selection.

Programming: selection

to set out the tests that will be carried out during testing

to decide how the project will be implemented

What is the purpose of a test plan in programming?

A {{}} error occurs when the program may run, but does not perform as expected.

A {{}} error happens when the program has incorrect syntax and will not run.

values that should be accepted as they are valid

values that should not be accepted and will cause an error

values that are at the edge of being valid

Match the test data type to its description.

Which of the following is an example of erroneous test data for a program that asks for an age (expected input: an integer)?

In the software development life cycle, {{}} is the stage that follows development and involves checking for errors.

{{}} is a way of expressing an algorithm that is independent of a specific programming language.

What is the missing stage of the software development life cycle?
Planning,
analysis,
{{}},
development,
testing,
implementation.

At which stage of the software development life cycle do you start to create a program?

a type of loop that repeats a block of code

a selection statement placed inside another selection statement

returns True if at least one condition is True

Match the logical operator to its function.

Match the relational operator to its meaning.
