Write the program in C++

1.

Design a function that processes an array of type int with the purpose of obtaining the max, min and average values of the array. Then use an array of size 10 initialized with random values in the range [50 100] to verify the correctness of the function ( call be function in the main by passing an array of 10 integers and get the max, min and average on the screen).
