Here's the algorithm: 1)Get a number to reverse as an input. 2)Declare two integer variables, varA and varB; varA for the reversed number(this has to be initialized with a value of 0), varB for the original number. 3)Now, until varB reaches 0, repeat this loop. 3-1)Multiply varA by 10. 3-2)Add thr remainder of (varB/10) to varA. 3-3) Divide varB by 10. 4)If the loop is finished and it's correctly coded, you will have a reversed number, and the value is stored via varA.

void Main(); { Console.Write("Enter the number to be reversed"); int n=Convert.ToInt32(Console.ReadLine()); int a,rev=0; while(n>0) { a=n%10; rev=rev*10+a; n=n/10; } Console.WriteLine(rev); }

void rev(int num) { int rev=0; while(num) { rev = (rev*10)+(num%10); num=num/10; } //Now Print The Number. }
