Help me

[Liam-McShane]

Right i have been given this task for college and none of us in our class have ever programmed before so we are total noobs. We where asked to:

 

"Create a low level (machine code) program to mimic an electronic stock control program which could be used on a fridge by enabling the following.

 

·       Entry of a number of items in the fridge (e.g. eggs) storing this in a specified location.

·       The continued deduction of eggs until either there are no eggs left or the end of the week is reached. This should be signalled by the user entering 0.

·       The output should then be the number of eggs which should be bought to make up the number."

 

Basically our teacher did one half for me and the other half for a friend and we merged our program to make the whole program. Now we took photos of us going through the program but we're not sure what the numbers entered mean and what the numbers in the register mean either. 

 

 

 

Thank you for your help (If it's even possible to help us)

So where is the actual program dude?

As far as i am aware we used a program called "Little Man Computer" to make the the program and run it. The Album is pictures of the program.

You can use arrays to store the information that is in use, but it's RAM hungry.

Post the program in github or something.

As bad as the photos are, the code is still fairly readable

 

Anyways Liam the number in the register is just a bit of extra memory in the CPU where the CPU is storing temporary numbers.  It is hard to see based on when you took pictures, but I am guessing after the READ if you enter say 11 the number will be 11 in the register (as READ reads into the register).  The store will then store the number in register to the memory address.

 

As for the numbers entered.  Well first is eggs you have, then eggs that you have used, and 0 being ending it.
