Question

Write a program in Matlab where the program plays a hot and cold game. The user answers two inputs: x=input('what is the x location of the object?') y=input('what is the y location of the object?') You write the program so that the computer plays the game. Pick a starting point. Program Calculates the distance to the object. Program picks another point, calculates the distance to the object. Program knows its at the right spot when the distance is less than 1. The program will consist of mostly loops and if-then statements. ONLY PROMPT THE USER TO INPUT THE "SECRET" X AND Y LOCATION. THE COMPUTER WILL FIND THE POINT. DO NOT KEEP PROMPTING THE USER TO KEEP GUESSING. IT IS THE PROGRAM'S JOB TO FIND THE POINT THE USER HAS CHOSEN. Program is finding a point the user picks in a 20X20 matrix. It also needs to have a counter built in so you know how many steps it takes the program to find the x,y coordinate. Points will be chosen using logic, not random.

Answer 1

The following information has been provided for the question above:

• "Screen shot of Matlab code" for understanding of code indentation.
• "Text format code" to copy and execute in your IDE.

NOTE: I used MATLAB R2017a IDE to execute this program code.

Screen shot of Matlab code:

Output:

Text format code:

%Computer will find the secret pick point by
%using20 x 20 matrix
computerSecretPickforX = randi([0 20], 1, 1)
computerSecretPickforY = randi([0 20], 1, 1)

%Prompt and read the input from the user
x=input('what is the x location of the object?')
y=input('what is the y location of the object?')

%Calculates the distance
calcDistance = sqrt((computerSecretPickforX - x).^2 + (computerSecretPickforY - y).^2);

% Verify the user guess input and computer pick is same or not
% If it is matched, then print the success prompt message,
% Otherwise using loop repeat the steps until the find the
% secret points
if x == computerSecretPickforX && y == computerSecretPickforY
    fprintf('Congrates! You got success')
else
    %While execute till condition is true.
    while true
        %Display message.
        fprintf("Not matched with computer secret point! Try again!\n")
       % Prompt the user to get x and y value.
        x=input('what is the x location of the object?')
        y=input('what is the y location of the object?')
        if x == computerSecretPickforX && y == computerSecretPickforY
          
            %Display message.
            fprintf('Congrates! You got success')
            break;
        end
        counter = sqrt((computerSecretPickforX - pointX)^2 + (computerSecretPickforY - pointY)^2);
        %Verify the secret point is very near match to
        %computer pick point then prompt the colder message,
        %otherwise prompt the hotter message
        if counter > calcDistance
            fprintf('Going colder...\n')
        else
            fprintf('Going hotter...\n')
        end
        calcDistance = counter;
    end
end
