Adrian asks - How will you make a loop to keep the user shopping

• FOR loop
• IF statement
• pray to god

Jacob asks - Explain how your algorithm functions efficiently and changes you can make to make it more efficient.

• I used various vaidations and checks in order to make sure that the user eventually makes a correct input if incorrect inputs are being made. One way I could make the program more efficient would be to shorten it.
• I used 6 seperated for loops full of validation to ensure correct input. One way I could make the program more efficient would be to make the program longer.
• My program is efficent because i used 2d arrays. I could make it more efficient by using 1d arrays
• My program is efficient because it uses minimal indications to the user to tell them what is going on, thus saving space within the code. I could make to program more efficient by removing all information statements from in the code.
