2.5 Translators of Languages

Question 1

What are assemblers responsible for?

Answer 1

Converting low-level assembly language into machine code.

Question 2

How do assemblers work?

Answer 2

Each line of assembly code is converted or looked up by the assembler and translates directly into one line of binary

Question 3

Define translator…

Answer 3

Any program that converts source code ( code written in a programming language) into machine code (binary)

Question 4

What are compilers and interpreters responsible for:

Answer 4

Converting high-level languages into binary

Question 5

How do compilers and interpreters have a one to many relationship

Answer 5

Each single line of high level source code written by a programmer translates into many lines of binary

Question 6

How do interpreters translate a high level language?

Answer 6

They take one line of high language program code and convert it directly into binary and then run it.

Question 7

Why are interpreters useful when debugging a program?

Answer 7

Because they will stop at the first line which contains an error

Question 8

What is a disadvantage of interpreters debugging a program?

Answer 8

The interpreter will require access to the whole source code each time it needs to translate it

Question 9

How are interpreters debugging a program inefficient:?

Answer 9

It’s a security issue, the code can be stolen. The code executes quite slowly,especially for large programs

Question 10

How do compilers translate high level language?

Answer 10

They take the entire program and converts it into object code which can be quite slow.

Question 11

Why can a compiler be better than an interpreter?

Answer 11

The compiled object code will run a lot faster than the interpreted version

Question 12

Why can an interpreter be better than a compiler?

Answer 12

If the program needs to be updated now, the original source code would have to be changed and a new version compiled and distributed

Question 13

What is IDE (integrate development environment)

Answer 13

A program which provides resources and tools with high level languages.

Question 14

What are some included tools of IDE?

Answer 14

• Multi-window editing
• Run Time Environment
• Built in translator
• Integrated debugger

Question 15

Why do most professional programmers use more complex IDE’s?

Answer 15

Because the y provide a whole host of extra features and resources to help them complete their complex programs faster
