Unit #6-04

Learning Outcome

At the end of this lesson, you will be able to:

• understand and use a 2D array (or list in python)

Review

• passing parameters

Lesson

• go over  2-D Arrays , Computer Based Problem Solving

Activity

• nil

Daily Assignment

• create a program that generates a 2D Array the size the user asks for

  • you need to get rows and columns

• using loops, randomly generate numbers between 1 and 50 and place them in the 2D-array

• do all of the above in the main() function

• then have a function that accepts the 2D array and finds the average of all the numbers

  • remember, loop inside of a loop!

  • no using a built in average function

  • display average to 2 decimal places

• read  over  2-D Arrays , Computer Based Problem Solving

Extra

• recreate the same above program in a second language

  • you MIGHT NOT be able change the size of the array dynamically like in Python

    • just pick a size for the row and column and assign them as constants
