What is Computer Science?

Wikipedia; the learning of techniques for computers

Curiosity.discovery; One of the three large areas of information related to computing

Oxford Uni; The study of the maths, techniques and structures, related to every kind of computing

Computer Science is the learning behind the creation of computer software, and studying the methods to optimism 
the capabilities of the given recourse.  

Why we need computer science; We need computer science to take full advantage of the use of  the
computer hardware we have at hand

I found another double popup problem, I forgot to engage the restartProblem on both catch types

The restartProblem bool need to be reseted, its stopping a button from working

15/10

Worked on comments

After completing entering and confirming customer details; put the number -4 in pizza choice textbox and click next

Invalid input should appear in a message and after exiting that message it will be as if the user didn’t enter the invalid piece of information

I had to add an index out of range catch

The double popup problem happened with this, had to add an if statement and more use of the restartProblem Boolean

Problem with confirming order with no number in the box goes into another double popup problem, because the method has to return the text. I fixed this by adding another Boolean and an if statement of the code in the button click to check there is text in the text box

Doing some testing with message boxes my main array doesn’t contain anything, there must be a problem with the writing or it is over written

The string for the final display doesn’t clear for the next input, I fixed this by clearing the string before it is written to.

The invalid input checking comes up when it isn’t meant to, in not delivery mode.

I think I may be clearing the text box before I read it some how ?

Need line break at the end of the detail method

The delivery cost is somehow set to the content of the name textbox

Pizzas 4-9 are shown when they aren’t meant to, there is no total cost.

What I still need to do

Testing throughout  whole process
I need to fix one more double popup problem
I need to fix the displaying of the final order, its possibiliy something todo with the calculations.
Then I need to comment t he rest of my code

I fixed the extra popup of the detail summery. It was caused because the invalid input was triggered in a returning method, so when it restarts for new input, it still has to return something to run; so the popup forces the user to restart the program again to get to the start. I fixed this by adding a Boolean to track if this problem is going to happen, this also meant I had to move and add other variables. Within this I also fixed the error checking, it was looking at the array for a invalid input but the starting values I added for other reasons stopped the detection. So I switched the check to the text boxes.

Working on check to see if there is a number in the name
