Programming for Engineers (ELEE1147): A Typical Format for an Examination Question An examination question will be structured in order to allow the awarding of marks, and marks that build up through the classification levels. For example: 3. Structures are important compound data structures in C++ and are often used to handle complex data (real and imaginary values) in signal collection systems. a) Implement the structure shown by Figure Q3 in a main/client function and with the following initialisation of the variables: fc = 415000; fs = 16000; delta_f = 0; buffer_count = 0; [4 Marks] b) With the use of example code, show how the contents of the implemented structure can be displayed to STDOUT. [6 Marks] c) There is a requirement to keep track on how many times the implementation of a struct such as Signal is called in a program. Describe (with supporting code if necessary) how the use of a static variable could be used for this purpose. In other words, does the use of int buffer_count achieve this? [5 Marks] d) How could the real and imaginary parts of a complex number, e.g.: (2.35 + 4.00j), be handled in an array? [5 Marks] #include<iostream> using namespace std; #define BUFFER_SIZE 8 struct Signal { float fc; // Carrier Frequency float fs; // Sampling Frequency; int delta_f; // Change of Carrier? int buffer_count; // Number of Buffers used double data[BUFFER_SIZE]; // The data, which could be complex }; Figure Q3 Dr D I Armour-Chélu December 2018 Faculty of Engineering and Science “Set the scene” All students should be able to answer this – the “4/10” / 3rd Here, we are starting to draw out the average/above average student – the “5-6/10” / 2:2 and 2:1 This is “tricky” and a student that reads beyond the current level of this course should be able to answer this – the “7-10/10” / 1st
