Question

In C++ Write a function called fillArray that will fill an array of any constantly declared array size variable with random numbers in the range of 1 - 100.

Write a function called printArray that will print an array of any size.

Write a third function called countEvens which will count and return the number of even numbers in the array.

In main create an array that holds 25 ints. Use your functions to fill, print, and count the number of even numbers. You should

Fill the array

Print the array

Print the number of even numbers in the array

What not to do:

global variables

cout in any function other than main and printArray

goto statements

Please don't forget countEvens

Your output should look like the following:

#include <iostream>
#include <ctime>
#include <cstdlib>

using namespace std;

void fillArray(int arr[], int size)
{
for (int i = 0; i < size; ++i) {
arr[i] = 1 + (rand() % 100);
}
}

void printArray(int arr[], int size)
{
cout << "Array is: ";
for (int i = 0; i < size; ++i) {
cout << arr[i] << " ";
}
cout << endl;
}

int countEvens(int arr[], int size)
{
int count = 0;
for (int i = 0; i < size; ++i) {
if (arr[i] % 2 == 0) {
count++;
}
}
return count;
}

int main()
{
srand(time(NULL));
int arr[25];
fillArray(arr, 25);
printArray(arr, 25);
int evens = countEvens(arr, 25);
cout << "Number of even numbers in array is " << evens << endl;
return 0;
}

Array is: 9 20 32 29 ? 25 65 38 2 30 94 14 97 99 23 ? 3? 61 22 2 15 б3 Number of even numbers in array is 10 Process exited after 0. return value 62 45 1628 seconds vith Press any key to continue . -
