Software Development

Question 1

Editor

Answer 1

Allows a programmer to enter, format and edit source code

Question 2

Automatic Formatting

Answer 2

Correctly indents code

Question 3

Automatic Line Numbering

Answer 3

Helps the programmer locate errors

Question 4

Automatic Colour Coding

Answer 4

Changes key words, literals and annotation to different colours

Question 5

Linker

Answer 5

A program which allows previously compiled code, from software libraries, to be linked together

Question 6

Libraries

Answer 6

A library is a collection of commonly used private functions and subprograms. These functions and subprograms can be called from within your program at any stage, but only when the appropriate library has been linked.

Question 7

Subroutines

Answer 7

These could be functions created by the user to create reusable code. Examples of subprograms include standard input/output routines, such as saving data to disk.

Question 8

Standard Functions

Answer 8

These can include standard mathematical operations such as square root or random number generators.

Question 9

Loader

Answer 9

A program which loads previously compiled code to memory

Question 10

Debugger

Answer 10

A program which helps locate, identify and rectify errors in a program.

Question 11

Error diagnostics / syntax error detection

Answer 11

Used when a program fails to compile or to run. Error messages are displayed to help the programmer diagnose what has gone wrong.

Question 12

Trace

Answer 12

A facility which displays the order in which the lines of a program are executed, and possibly the values of variables as the program is being run.

Question 13

Break Point

Answer 13

A facility which interrupts a program on a specific line of code, allowing the programmer to compare the values of variables against expected values. The program code can the usually be executed one line at a time. This is called single-stepping

Question 14

Variable watch

Answer 14

A facility that displays the current value of any variable. The value can be ‘watched’ as the program code is single-stepped to see the effects of the code on the variable. Alternatively a variable watch may be set, which will interrupt the program flow if the watched variable reaches a specified value

Question 15

Memory inspector

Answer 15

A facility which will display the contents of a section of memory.

Question 16

Statement Completion

Answer 16

Ide will complete a statement such as an ‘end if’ to an ‘if’ statement.

Question 17

Code optimisation

Answer 17

Warning message when variables have been declared but not used.
