Programming & Computer Science Answers

Using AIT as a case study, discuss a simple networked system which could be useful at the entrance of the university in enforcing some of the COVID- 19 protocols

Discuss how you would link together the two campuses of AIT (Sea View and Knowledge City), discussing the choice of technologies to be used based on the distance between the two campuses and category of network size it falls under. Justify your choices.

Discuss the IT-related challenge(s) you face at the AIT Computer-Lab(s),

giving reasons for the challenge(s) and how the challenge(s) could be resolved. In addition, discuss the topology and architecture used the lab(s)

Discuss a simple networked system that could be used at the entrance to an examination hall at AIT in order to eliminate the manual checking of examination chits and ID cards during an exam session. Assemble such a system and discuss all the components of the system and how they function in detail.

Discuss how you would network AIT-Sea View campus, taking into account the various sections of that campus (computer labs, health clinic, offices, security post, etc), discussing the choice of technologies, devices, topology/topologies, network types, protocols and anything else you would use and justifying your choices.

Assemble a Server computer based on your budget (state the amount in Ghana Cedis), discussing the type of components (giving their exact names, model numbers, types, cost, architecture, etc.) you would need and give reasons why you need them.

Define a class Pairs with two integer data members, f and s, where f represents

the first value in the ordered pair and s represents the second value in an ordered

pair. Write a program to test all the overloaded operators in your class definition.

Overload the stream extraction operator >> and the stream insertion operator << as

friend functions so that objects of class Pairs are to be input and output in the

form (5,6) (5,-4) (-5,4) or (-5,-6).

Overload binary operator + as a friend function to add pairs according to the rule

(a,b) + (c,d) = (a + c, b + d)

Overload operator – as a friend function in the same way, i.e. according to the rule

(a,b) - (c,d) = (a - c, b - d)

Overload operator * as a friend function on Pairs and int according to the rule

(a,b) * c = (a * c, b * c)

Overload the +, - and * operators for objects of class Pairs, as member functions. Also, define the class Pairs as an ADT that uses separate files for the interface and the implementation.

An odometer is an instrument used for measuring the distance travelled by a vehicle. Define a class called Odometer that can be used to track fuel and traveling distance for a car. Include private member variables to track the distance driven and the fuel efficiency of the car in kilometres per litre. The class should have a constructor that initializes these values to 0. Include a default constructor to initialize both member variables to zero, a member function to reset the odometer to zero km, a member function to set the fuel efficiency, a member function that accepts km driven for a trip and adds it to the odometer’s total, a member function that returns the number of L of fuel that the car used since the odometer was last reset, and a destructor. Use your class with a test program that creates odometers for different cars with different fuel efficiencies. Let the cars do several trips. Reset the odometers at the start. Display the distance and the litres of fuel consumed after each trip. 

Write a program to find the minimum number of notes required for the amount M. Available note denominations are 500, 50, 10, 1.

Given

M = 1543, it can be written as1543 = 3*(500) + 3*(50) + 0*(10) + 1*(3)Then the output should be

500: 3 50: 0 10: 4 1: 3

sample input=1543 output is 500: 3 50: 0 10: 4 1: 3

sample input is=1259 and output is 500: 2 50: 5 10: 0 1: 9
