error message

Feb 17, 2012 at 10:59pm
Hello again,
I created a program that will generate an array from a random number. the program will calculate sum, average, and show the larges and smallest number in the array. after I wrote the code I functionalized it, meaning I created individual functions for the sum, aver, larges and smallest. after this i got the following error message, error C2109: subscript requires array or pointer type. why did this show up after i created different functions. All the errors seem to be at the "lcv" locations. Thank You for your help.

You didn't declare the array number anywhere.

@Wisely Done

Thanks for your response. I declared the array on line number 8 but the problem was not corrected. Do you have any other ideas that might solve this problem. Thank you again for your help in this matter.

In your functions you are hiding the global array number with parameters named number.
Feb 18, 2012 at 3:49am
All of your functions are asking for variables to be passed, but your prototypes and your function calls don't pass them anything.
