WriteLine reversDigits num ;. StringBuffer string. Python 3 program to reverse a number. Now, the value of n is which is greater than 0. Therefore, loop will be executed. When we divide any number by 10 then the last digit of that number is remainder. In this case, we are dividing by 10, that means the value of rem becomes 5.

This is the most important statement to reverse a number in c programming. In the first statement, we got the last digit as a remainder.

Now, we have to make this last digit as the first digit. So, this statement will help us. So, when we execute this statement, then the value of rev becomes 5. You can put the values of rev and rem in the above expression, then the value of rev becomes 5. Now, we have got our first digit i. So, we will have to find our another digit i. How could we do this? Same procedure we will have to follow. Because we already got our first digit i.

For example, the given number is , then the reverse of this number will be We can reverse the numbers or characters using various loops or combinations of loops as well as arithmetic operators. The logic for a reverse number is as follows:. In this section, we are going to see how to reverse a number using various methods like while loop, recursion, for loop and do while loop with the help of examples. While the loop gets executed several times until the condition matched. The condition will differ based on the requirement of the program.

While loop first checks the condition, and then start the loop. If the given condition is true then it will transfer the flow control to the statements defined in the while loop. If the given condition is false then it will transfer the flow control to the statements that are defined outside the while loop.
