使用数组作为参数的Caling函数

I'm having some difficulty with my syntax. The purpose of the below program is to print an array of 20 random numbers, find the max of the array and then print the array and the max. I've got the sections to initialize and create the array without any problem, but my issue is with the find_max function. In the main function, I'm trying to work out the syntax to call my find_max function there so I can print the results. If anyone can help to fix my syntax, I'd really appreciate it.
