Pseudo code is a mix of English and code. I'm seeing a lot of English but little or no code.
Saying "add up 10 items. divide by 10" won't suffice. write down how you will do this.
for example:
SUM = 0
LOOP counter FROM 0 TO 10
SUM = SUM + price[counter]
ENDLOOP
AVERAGE = SUM / 10
putting this into C++ code is a lot easier than just plain English
