Software engineering #7

Question 1

Another phrase for Software development environment?

Answer 1

Integrated Development Environments

Question 2

What is IDE?

Answer 2

Um…

• Provides programmers various tools to create programs

Question 3

Name 11 fucking facilities

(IDE)

Answer 3

• Editor
• Compiler
  • Interpreter
• Linker
• Loader
• Debugger
• Trace
• Break point
• Variable watch
• Memory inspector
• Error diagnostics

Question 4

Explain editor

(1 of the facilities for IDE)

Answer 4

Allows programmer to enter, format and edit source code

Question 5

Explain compiler

(1 of the facilities for IDE)

Answer 5

*Converts source code into executable machine code
*Once compiled, can be run any time

Question 6

Explain interpreter

(1 of the facilities for IDE)

Answer 6

• Converts each line of source code in machine code
  (don’t mix up with compiler)
• Executes it as each line of code is run
• Conversion processed is run
• When the program needs to be run

Question 7

Explain linker

(1 of the facilities for IDE)

Answer 7

• Program that allows previously compiled code
• From software libraries
• To be linked together

Question 8

Explain loader

(1 of the facilities for IDE)

Answer 8

Program which loads previously compiled code into memory

Question 9

Explain debugger

(1 of the facilities for IDE)

Answer 9

Program which helps locate, identify and rectify errors in program

Question 10

Explain trace

(1 of the facilities for IDE)

Answer 10

• Displays the order in which lines of program are executed
• And possibly values of variables as it’s being run

Question 11

Explain break point

(1 of the facilities for IDE)

Answer 11

• Interrupts program on a specific line of code
• Allows programmer to compare the values of variables w/ expected values
• Program code can be executed one line at a time <– single-stepping

Question 12

Explain variable watch

(3 separate bullet points)

(1 of the facilities for IDE)

Answer 12

• Displays current value of any variable

*Values are ‘watched’ when code is “single-stepped”
* To see effects of code on variable

• Alternately, if it’s set, can interrupt program flow
• if watched variable reaches specified value

Question 13

Explain memory inspector

(1 of the facilities for IDE)

Answer 13

• Displays the contents of a section of memory

Question 14

Explain error diagnostics

(1 of the facilities for IDE)

Answer 14

• Used when program fails to compile/run
• Displays error messages to help programmer diagnose problem

Question 15

What are libraries

(IDE related)

Answer 15

• Collection of commonly used “private functions” and “subprograms”
• Can be called from within program, with the right library linked

Question 16

An example of private functions?

(libraries)

Answer 16

*Standard mathematical operations

( square root, random number generator )

Question 17

An example of subprograms

(libraries)

Answer 17

• Standard input/output routines

( such as saving data to disk)

Question 18

2 Advantages of standard libraries?

(libraries)

Answer 18

• Time saved for a programmer, can use these stuff stored in library
• Programs will contain less code, easier to maintain

Question 19

Is it possible to create your own custom library?

(libraries)

Answer 19

Yes.
