An array is a type of data structure that contains a number of homogeneous data type elements under a same/common name. Array is used for storing a large amount of homogeneous data type. Array is used for making the searching and sorting techniques.

Now, we will see how to create a C# program that counts the number of odd terms and even terms in an array.

First, open Visual Studio and create a project of Console App.

Then, write the following code in the project.
  1. using System;
  2. using System.Collections.Generic;
  3. using System.Linq;
  4. using System.Text;
  5. using System.Threading.Tasks;
  6. namespace Number_of_even_and_odd_terms_in_an_array {
  7. class Program {
  8. static void Main(string[] args) {
  9. int i, n, even = 0, odd = 0;
  10. Console.WriteLine("Enter the number of elements to be inserted: ");
  11. n = Convert.ToInt32(Console.ReadLine());
  12. int[] a = new int[n];
  13. Console.WriteLine("Enter the array elements:");
  14. for (i = 0; i < n; i++) {
  15. a[i] = Convert.ToInt32(Console.ReadLine());
  16. }
  17. for (i = 0; i < n; i++) {
  18. if (a[i] % 2 == 0) {
  19. even = even;
  20. even++;
  21. } else {
  22. odd = odd;
  23. odd++;
  24. }
  25. }
  26. Console.WriteLine("Number of even terms are: " + even);
  27. Console.WriteLine("Number of odd terms are: " + odd);
  28. Console.ReadLine();
  29. }
  30. }
  31. }
The following screen will appear.



Run the application to see the output.



This is how we create a program that counts the number of odd terms and even terms in an array.
