Question

Creates MATLAB program that acts like an user-machine interface which will help the user to know about any updates about COVID-19 only in the particular states in the USA including the areas affected and the number of registered positive cases along with number of deaths.

State = ["WASHINGTON", "CALIFORNIA", "VIRGINIA", "TEXAS", "MARYLAND", "COLORADO", "OKLAHOMA", "KANSAS", "LOUISIANA", "INDIANA", "PENNSYLVANIA", "NEW JERSEY", "NEW YORK", "MAINE", "NEW MEXICO", "ARIZONA"];

Cases = [1376, 1030, 105, 307, 107, 277, 46, 35, 392, 60, 206, 742, 5711, 52, 35, 45];

Deaths = [74, 18, 2, 5, 1, 4, 1, 1, 10, 2, 1, 9, 38, 0, 0, 0];

FOR EXAMPLE* WASHINGTON has 1376 cases of COVID-19 in which 74 deaths.**

****Should make use of the use given data set above.****

Write MATLAB code that operationalizes the algorithm. The code will need to use input, vectors, repetition (while loop), selection/decision structures (if-end, if-elseif, and/or if-else), and output in meaningful ways. Program should use at least one input statement in your MATLAB code. Input statement should not be used for the data set.

The program should ask the user to enter the name of the state and it should process the data about the cases and deaths (according to the data in vectors given). This program should make use of while loops and selection/decision structures too.

The program will also create an deaths/cases ratio which will determine if it's safe to travel to that particular state or not. It should print a message regarding it.

*FOR EXAMPLE**ARIZONA has 0 deaths, implying 0 deaths/cases ratio. The program should print a message something like, "It is safe in Arizona, but it is advisable to carry all the necessary protections.."

**The maximum threshold for death, case ratio can be any number chosen by YOU**..

Answer 1

In this problem, we need to write a matlab code that will act like a user-machine interface. The program should ask the user to enter the name of the state, and then the code will start to process the data about the cases and deaths. It should use while loops.
The program will also create a death/case ratio to determine if the state is safe to travel and based on that it prints a message.
The corresponding matlab code is shown below

clear all
clc

%% dataset for each state of USA
State = {'WASHINGTON'; 'CALIFORNIA'; 'VIRGINIA'; 'TEXAS'; 'MARYLAND'; 'COLORADO'; 'OKLAHOMA'; 'KANSAS'; 'LOUISIANA'; 'INDIANA'; 'PENNSYLVANIA'; 'NEW JERSEY'; 'NEW YORK'; 'MAINE'; 'NEW MEXICO'; 'ARIZONA'};
Cases = [1376, 1030, 105, 307, 107, 277, 46, 35, 392, 60, 206, 742, 5711, 52, 35, 45]';
Deaths = [74, 18, 2, 5, 1, 4, 1, 1, 10, 2, 1, 9, 38, 0, 0, 0]';

%% performing while loop
while(1)
  
    %% user input
    UserInput = input('insert the name of the state where you want to travel \n','s');
    count = 0; % check whether the inserted state is in the database
  
    for i = 1:length(State)
        val = strcmp(cell2mat(State(i)), UserInput); %% compare the string
      
        if(val == 1) %% if the inserted string is in the database
            count = 1;
            index = i;
            C_state = Cases(index); % obtain the no of cases;
            D_state = Deaths(index); % obtain the no of deaths;
          
            %% display the result
            disp('The inserted State is')
            disp(UserInput)
            disp('The number of cases in that state is')
            disp(C_state)
            disp('The number of deaths in that state is')
            disp(D_state)
          
            %% calculate death/case ratio
            r_state = D_state/C_state;
            if(r_state == 0) %% thresold limit chosen to be 0
                disp('The inserted state is safe, but it is advisable to carry all the necessary protections.."')
            else
                disp('It is advisable not to travel in this state')
            end
        end
    end
  
    if(count == 0)
        disp('inserted state is not in the database!!!')
    end
  
end
