Strong number is a special number whose sum of factorial of digits is equal to the original number. #include { Then using while loop the reverse number is calculated. 1) The number is called a palindrome if a number is equal to reverse of its number. It is a number which remains same even when the number is reversed. There are two additional while-loops.While. If still not a palindrome, take the sum of the last number and it's reverse and add that together, for a maximum of 10 tries. If the numbers are the same, then the number is a palindrome ,else it is not; Now that we have the algorithm let us convert it into code by following the similar logic. Otherwise, it is not a Palindrome number. Let’s see how to check if a number is a palindrome or not using a While loop. It is evident that letters form mirror images on reversal. temp_number = number; //store number to temp_number Thus the program execution is completed. If the numbers are the same, then the number is a palindrome ,else it is not; Now that we have the algorithm let us convert it into code by following the similar logic. If a number remains same, even if we reverse its digits then the number is known as palindrome number.

Step by step descriptive logic to check palindrome number. Write a program to check whether given number is Palindrome or not using do-while loop. There are many other numbers available which are a palindrome. + 4! If a number remains same, even if we reverse its digits then the number is known as palindrome number. reverse_number = reverse_number + number % 10; }. scanf("%s", string); // takes string as a input Then it assigns the value of a=n (a=121). This process repeats again and again and terminates when the given condition becomes false. Find your own palindrome number with the above method. Input a number from user. If both reverse and temporary variables, matches, print it is a palindrome. number = number / 10; + 5! Let’s see how to check if a number is a palindrome or not using a While loop. C Program to Check Armstrong Number In this example, you will learn to check whether an integer entered by the user is an Armstrong number or not. Sentences are handled correctly. if(temp_number == reverse_number) // check reverse number with original number { Inside the loop, the reversed number is computed using: rev = rev*10 + remainder; The syntax for while loop is: while (test-expression) { // body of while } How while loop works? }. printf("Given number is palindrome"); //if match, print palindrome In this article we have shared two C programs to check if the input number is palindrome or not. while (number > 0) Now we compare the reversed number with the original number. 1) Using Stack 2) Using Queue 3) Using for/while loop. s=s*10+r (s=12*10+1) So s=121. As we discussed earlier, palindrome is the same result that you get after reversing. Let us check if a number is a palindrome or not by using C++ program. It’s more like mirror of its own. scanf("%d", &number); // takes value from user Logic to check palindrome number. Sentences are handled correctly. Example: RACECAR Output: Yes, a Palindrome string. In this article you will learn about c program to check palindrome number. }while(number != 0); Logic to check Strong number. Related: C program for Palindrome number using For Loop. Recommended for you So we can say that 121 is a palindrome. It prints 121 is a palindrome number. C++ PROGRAMS. After that again the condition will be checked. s==n (121==121) if condition is true. To understand below example, you have must knowledge of following C++ programming topics; For Loop in C++ and Reverse Number Program in C++.
