How to create a program that repeats itself?
显示 更早的评论
I want this program to repeat itself after giving an output (ask input again and calculate again). I don't know how to do that can someone help me?
t=36; %total number of lectures
b=0;
while b==0
p=input('Enter Number of Lectures Attended \n');
if p>36
fprintf('Error, note that the total number of lectures are 36. \n')
else
b=1;
end
end
a=(p/t)*100; % this calculates the percentage attendance
if a>=75
fprintf('The student does not have short attendace. \n')
else
fprintf('The student has short attendace. \n')
end

Try this:
% Demo by Image Analyst.
clc; % Clear the command window.
fprintf('Beginning to run %s.m ...\n', mfilename);
close all; % Close all figures (except those of imtool.)
clearvars;
workspace; % Make sure the workspace panel is showing.
format long g;
format compact;
fontSize = 16;
buttonText = '';
totalNumberOfLectures=36; % Total (max) number of lectures
while ~contains(buttonText, 'Quit', 'IgnoreCase', true)
numLecturesAttended = -1; % Initialize
while numLecturesAttended < 0 || numLecturesAttended > totalNumberOfLectures
numLecturesAttended=input('Enter Number of Lectures Attended : ');
if numLecturesAttended < 0 || numLecturesAttended > totalNumberOfLectures
fprintf('Error. Note that the total number of lectures is %d.\nEnter a number between 0 and %d (inclusive).\n', ...
totalNumberOfLectures, totalNumberOfLectures)
end
end
percentAttended = (numLecturesAttended/totalNumberOfLectures) * 100; % This calculates the percentage attendance
if percentAttended >= 75
fprintf('The student does not have short attendance. \n')
else
% Did not attend at least 75% of their classes.
fprintf('The student has short attendance. \n')
end
% See if they want to do another one.
promptMessage = sprintf('Do you want to ask again,\nor Quit processing?');
titleBarCaption = 'Continue?';
buttonText = questdlg(promptMessage, titleBarCaption, 'Yes - Ask Again', 'No - Quit', 'Yes - Ask Again');
if contains(buttonText, 'Quit', 'IgnoreCase', true)
break;
end
end
fprintf('Done running %s.m\n', mfilename);
