Answer:
// Program is written in Coral Programming Language
// Comments are used for explanatory purpose
// Declare and input n; n stands for the number of input data
integer n
n = Get next input
// Declare and initialise two Variables to 0;
// The first Variable Sum, is used for addition and the second, Max is used for the max
integer sum
integer max
Sum = 0
Max = 0
// Declare and intialise Variable count to hold the number of positive input data
integer count
count = 0
// Declare array. The array is used to hold all input data
integer array(n) Arr
// Declare iterating variable I
integer i
//Use the following iterative statement to input array data
for i = 0; i < Arr.size; i = i + 1
Arr[I] = Get next input
if Arr[i] >= 0
Sum = Sum + Arr[i]
count = count + 1
if Arr[i] >= Max
Max = Arr[I]
// Declare Variable average
float average
//Calculate and print average
average = Sum/count
Put average to output
Put Max to output
