Intergrated Development Environment

Question 1

Editor

Answer 1

Allows a programmer to enter format and edit source code

Question 2

Compiler

Answer 2

Converts source code to machine code. Once compiled a program can be run at any time

Question 3

Interpreter

Answer 3

Converts each line of source code into machine code and executes each line of code is run

Question 4

Linker

Answer 4

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

Question 5

Question 7

Trace

Answer 7

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 8

Break point

Answer 8

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 then usually be executed one line at a time. This is called single-
stepping

Question 9

Variable watch

Answer 9

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 10

Memory inspector

Answer 10

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

Question 11

Error diagnostics

Answer 11

Used when a program fails to compile or to run. Error messages are displayed to
