IDE

Answer 1

Integrated Development Environment; Provides programmers with tools that are needed to create computer programs

Question 2

Debugger tools

Answer 2

A range of facilities enabling the programmer to investigate conditions when errors occur e.g. break points, watch window

Question 3

Source code

editor

Answer 3

Allows programmers to enter and edit code

Question 4

Answer 4

Highlighting syntax errors before code is translated

Question 5

Intellisense

Answer 5

Predictive text for programmer to help with correct use of commands and variable names

Question 6

Error diagnostics

Answer 6

Helps the user to identify compilation errors (syntax errors)

Question 7

Trace/stepping

Answer 7

Showing which lines of code are executed in which sequence

Question 8

Breakpoint

Answer 8

Allow program stop at certain point to check values of variables against expected ones

Question 9

Variable watch

Answer 9

Tracking a variable’s value as code is executed

Question 10

Compiler

Answer 10

Provides programmer tools to convert the source code into machine code so program can run outside the development environment.
(Lexical/Syntax/Semantic Analysis and Code Generation)

Question 11

Automatic formatting

Answer 11

Correctly indents code

Question 12

Lexical Analysis

Answer 12

Converts input stream into tokens
Comments and unneeded space removed
Error messages are generated if needed

Question 13

Syntax Analysis

Answer 13

Symbol table/dictionary produced
Tokens checked for fit to the grammar using BNF-type rules.
If not, error messages produced.

Question 14

Semantic Analysis

Answer 14

Checks all variables are declared and used.
Checks that variables have right data type (real number as integer).
Checks that operation is legal for type/no mixed mode arithmetic.

Question 15

Code generation

Answer 15

Machine code is generated

Code optimisation may be employed

Question 16

CASE tool

Answer 16

(Computer Aided Software Engineering tool)
