Introduction
I have used Visual Studio 2012 for debugging purpose. But you can use any version of visul studio as per your availability.
using System; class Program { static void Main() { int[] arr = new int[100]; int i, num, evennum, oddnum; ////Reads size and elements in array Console.WriteLine("Enter size of the array: "); num = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("Enter "+num+" elements in the array: "); for(i=0; i<num; i++) { arr[i] = Convert.ToInt32(Console.ReadLine()); } evennum = 0; // Assuming 0 even numbers oddnum = 0; // Assuming 0 odd numbers for (i = 0; i < num; i++) { /* If the current element of array is evennumber then increment evennumber count */ if (arr[i] % 2 == 0) { evennum++; } else { oddnum++; // increment oddnumber count } } Console.WriteLine("Total even numbers: "+evennum); Console.WriteLine("Total odd numbers: " + oddnum); Console.ReadLine(); } }
