Answer ANY five questions.
All questions carry equal marks.
Examiners: Mr. D. O’Donovan
Mr. D. Denieffe
Dr. P. O’Sullivan
1. (a) Describe the operation of the Binary Search algorithm. Use the list:
1 5 7 8 10 15 20 23 25 40
Demonstrate the operation of the Binary Sort algorithm by searching for 7. [8 %]
(b) Write code to implement the Binary Search algorithm in BASIC. [12 %]
2. (a) Define a user-defined data type, called ‘sample’, capable of storing two integer co-ordinates –
called amplitude and time. [5 %]
(b) Declare an array of 300 samples as defined in (a) called ‘sampleData’. [3 %]
(c) Write Visual BASIC code such that when the command Button ‘Read’ on the program form
is clicked i.e. ‘Read_click()’ event occurs, the sample data from a file called ‘c:\input.dat’ is
loaded into the array defined in (b). The data should be read until the end of file is reached.
The data is stored in the format: amplitude1, time1, amplitude2, time2, amplitude3, time3,
etc. [6 %]
(d) Write Visual BASIC code for the button ‘Average_click()’ event to calculate the average of
the amplitude values extracted from the file in (c). [6 %]
