​Key features - Iterative development process

Development process is completed in set stages which are completed one after the other.
Documentation is produced at every stage of the development process.
The client is heavily involved at the start of the project in order to produce the requirements specification. They are also involved at the evaluation stage.
Testing is done once a completed solution has been developed.
Teams of developers with particular skills work together with some interaction between teams at the end/beginning of a stage.

​Key features - Agile development process

Emphasis is placed on the development of various prototypes which are developed to form a completed solution.
There is limited documentation created for the solution.
The client is heavily involved throughout the development process, they give feedback on the prototypes which helps to shape the final solution.
Testing and evaluation is completed throughout the development process.
There is a heavy emphasis placed on teamwork and face to face communication between developers and the client.

Fill in the Blank

What is the scope of the variable index?

Fill in the Blank

A function has been written to generate numbers until a limit value is reached. The function receives three parameters and calculates an array of integers by adding the previous two numbers to create the next one. Numbers are generated while they are less than the limit given.  For example, if the parameters are first = 3, second = 6 and limit = 31.

 

Then the numbers generated will be: 

3, 6, 9, 15, 24

 

All numbers in the sequence must be smaller than the limit.  The function code is shown below.

A logic error in the code means an incorrect array of numbers if generated.  The trace table below shows the line numbers where a variable has changed.

State the missing value at A.
