Mumz [18]

Answer:

The explanation is for 10 inputs though. You'd have to follow these steps to find input 50 numbers.

Explanation:

This is how I wrote it in the Plain English programming language which looks like pseudo-code but compiles and runs (to save you all the rest of the steps):

To run:

Start up.

Write "Enter 10 numbers separated by spaces: " on the console.

Read a reply from the console.

Loop.

If the reply is blank, break.

Get a number from the reply.

Add 1 to a count.

Add the number to a total.

Repeat.

Write "The total is: " then the total on the console.

Put the total divided by the count into an average.

Write "The average is: " then the average on the console.

Refresh the screen.

Wait for the escape key.

Shut down.
