Application Generation

Question 1

Compilers

Answer 1

Complier - Read and Compiles the whole code
Advantages:
- Saves Copy of code
- Hard to edit the code
- Becomes Executable File
- Quicker after First Load
Disadvantages:
- initially first run slow
- doesn’t spot errors immediately

Question 2

Interpreter

Answer 2

Interpreter - Read and compiles line by line
Advantages:
- initially quick
- Spots errors immediately
Disadvantages:
- doesn’t save a copy
- easy to edit
- longer to run after first step

Question 3

Intermediate Code

Answer 3

• Simplified code
• runs on any computer through a VM
• sections of the intermediate code can be generated from source code

Question 4

Assembler & Cross Assembler

Answer 4

Assembler Coverts assembly code into machine code - Outputs code intended to run on the cpu the interpreter runs on

Cross Assembler- outputs code intended to run on a different CPU

Question 5

COMPILATION

Answer 5

3 STAGES
First Stage:
•Lexical Analysis - Removes white spaces and comments & then adds remaining characters to a tokens then added to a token table
•Syntax Analysis - checks the structure of the program and whether it meets the program requirements
