Write in Matlab

A restaurant sells five different desserts whose prices are shown in the following table:

Write a Matlab program to display the above menu to the user. The program then prompts the customer for a key board entry of a series of pairs of numbers as follows.

Dessert Number:

Quantity sold:

The program should then use the switch statement to obtain the total price for the selected product. The program should also display the results after the computation using appropiate format statements.

Solution

MATLAB CODE

Price = [2.98 4.5 9.8 4.5 3.85];
fprintf(\'MENU\ \');

fprintf(\' _______________________________________________\ \');
for i =1:length(Price);
    fprintf(\'|\\t%d\\t\\t|\\t%2.2f\\t\\t|\ \',i,Price(i));
    fprintf(\' _______________________________________________\ \');
end
ext = 1;
fprintf(\'Please enter your order. Press 0 to stop ordering! Thank you :)\ \');
while ext
    Number(ext) = input(\'Dessert Number:\');

        case 1
