Hi Anand, Sibeesh already written the solution for your problem but some small mistakes are there. You can try this one also. Here i have written One Function which will return you the average of the number in the string. public double Average(string str) { int sum=0,len; len=str.Length; for(int i=0;i { sum=sum+Convert.ToInt32(str[i]); } return sum / len ; }

Try this. Note that, to avoid the use of integer arithmetic when calculating the average, you need to cast at least one of the operands to double: using System; class Average { static void Main() { Console.WriteLine("Input a series of non-negative integers ending with -1
"); int sum = 0; int n = 0; while(true) { Console.Write (" : "); int i; bool isValid = int.TryParse(Console.ReadLine(), out i); if (!isValid || i { Console.WriteLine("Ignoring input as invalid"); continue; } if (i == -1) break; sum += i; n++; } double average = (double)sum/n; Console.WriteLine("
Average of the {0} non-negative numbers is {1}", n, average); Console.ReadKey(); } }

You can do it as the following . Please note that I have not tested this code. using System; class Program { static void Main() { int sum,avg; const string s = "0124"; foreach (char c in s) { sum=sum+convert.toint32(c); } avg=(sum)/(s.Length) } }
