There is one more way rather than recursion and that is writing a loop in the middle of the string to check if the corresponding letter at each end is the same or not. If you are working on a programming language where string reversal is easy but it will require an extra amount of space to store that reverse string in another way such as recursion require more stack frame. Also, the matches required in completely equal to half of the string length. By just using for loop you can perform all the operations and it saves a large amount of time and space when it comes to programming because in this case, you neither have to modify the existing string nor write another variable to memory. Suppose that in your project you want to match the first string/element with the last one then the second element/string to the second last one and so on and the string will be palindrome if you reach to the middle.Let us check if a number is a palindrome or not by using C++ program.Ĭout << " The reverse of the number is: " << reverse << endl Ĭout << " Entered number is a Palindrome." Ĭout << " Entered number is not a Palindrome." We will take a number as an input from the user and check if it is a palindrome or not. One more example using a do-while loop will also explain the algorithm we discussed in the introduction. If the condition satisfies then it will print that the number is palindrome otherwise if the condition fails it will go to else part and will print that the number is not a palindrome. If the number becomes 0 then it will check if the temporary variable is equal to the sum or not. The above code will take a number as an input from the user and put it into a temporary variable as you can see that sum is already 0 it will use a while loop until the number becomes 0 and as the code is written it will perform the operation as written after while loop. Void countPalindrome(int minimum, int maximum) function to prints palindrome between a minimum and maximum number Function to check if a number is a palindrome or not. For example range is How to Implement palindrome in C++?īelow are the different examples to implement palindrome in c++. If same then the number is a palindrome.ĭon’t worry here is an example suppose we have to print palindromes between the given range of numbers.After reversing compare it with a temporary variable.For example, we reverse the 151 results will be 151 so it is a palindrome number. The palindrome number means the number will be the same after reversing any number.
