Guys help fast please!!

Write a C++ program to prompt the user to input N
positive integers; when the user enters - 1 the
program input will stop and implement the needed
functions (5 points)
• Function to calculate the count of input positive
number.
(5 points)
• Function to calculate the average of even
integers
(5 points)
• Function calculate the max of odd
integers
(5 points)
• Function calculate the sum of integers <=
(5 points)
Output the result of the above
operations
points)
50
HINT
1- Functions should be called by Value
2- Functions should return a value to be used for output in final point.

Where are the following questions

Just trying to get some points : p sorry bro

Public static int mystery(int a[], int x) {     int c = 0;     for(int i = 0; i < a.length; i++) {        if (a[i] == x) c++;     } return c; }the method counts how many times an integer shows up in an integer array.the c variable is declared in the method to keep track of how many times the certain value has shown up.the for-loop loops through the entire array.the line    if (a[i] == x) c++;   checks if each element of the array is equal to the inputted integer to check. for each number in the array that is equal to the inputted integer x, the c variable will be incremented by 1. otherwise it will do nothing.then c is returned at the end of the loop.for example, if we have, in the main method with the mystery method coded in the class:     int arraytest[] = {2, 23, 23, 23, 3};     int testme = 23;     int count = mystery(arraytest, testme);     system.out.println(count); then the print out will be    3 because there are three 23s in that array.
