Which development methodology requires more client involvement ?

• Agile

• Iterative

• They are both the same

The purpose of a program is to enter the names of pupils, their prelim mark and assignment mark. Their percentage and grade is then calculated and displayed on screen

What are the functional requirements of the program in terms of inputs, processes and outputs?

• Inputs: pupil names

  Processes: find out grades

  Outputs: grades

• Inputs: pupil names, prelim marks, assignment marks

  Processes: find out grades

  Outputs: percentages, grades

• Inputs: pupil names, prelim marks, assignment marks

  Processes: calculate percentages, find out grades

  Outputs: percentages, grades

• Inputs: pupil names, prelim marks,

  Processes: calculate percentages, find out grades

  Outputs: percentages, grades

The scope and boundaries for a project must be set during the analysis stage.

What might be included in the scope?

• program, test plan, time limits

• design, program, time limits

• design, program, test plan

• design, program, test plan, time limits

The scope and boundaries for a project must be set during the analysis stage.

What is meant by the boundaries?

• limits, assumptions

• limits

• assumptions

• design, limits, assumptions

A program is to calculate the volume of a cuboid

The top level algorithm could be written as

1: enter dimensions

2: calculate volume

3: display volume

Which of the following would give the correct data flow for the program?

• 1: enter dimensions(in: length, breadth, height out: length, breadth, height)

  2: calculate volume(in: length, breadth, height, out: volume)

  3: display volume(in: volume)

• 1: enter dimensions(in: length, breadth, height out: length, breadth, height)

  2: calculate volume(in: length, breadth, height, out: length, breadth, height )

  3: display volume(in: length, breadth, height, out: volume )

• 1: enter dimensions( out: length, breadth, height)

  2: calculate volume( out: volume)

  3: display volume(in: volume)

• 1: enter dimensions(out: length, breadth, height)

  2: calculate volume(in: length, breadth, height, out: volume)

  3: display volume(in: volume)

A program requires separate arrays to store pupils names, marks and grades.

How would these be stored?

• In an array of records

• In parallel arrays

A program requires to store pupils names, marks and grades as efficiently as possible.

How would this data be stored?

• In an array of records

• In parallel arrays

A record is to be set up to hold a pupil's name, prelim mark and whether they have passed the SDD unit

How would this structure be defined?

• pupilDetails{name as STRING, prelim as INTEGER, unit as BOOLEAN}

• pupilDetails {name as STRING ,prelim as STRING , unit as INTEGER}

• pupilDetails{name as STRING, prelim as INTEGER}

• pupilDetails{name as STRING, prelim as REAL, unit as BOOLEAN}

What is the scope of a local variable?

• the whole program

• only one module

What is the scope of a global variable?

• the whole program

• only one module
