# palindrome number in c using function

There are so many Program methods to get the Palindrome of number and string we will see it one by one. In this program we will use function to check whether the entered number is Palindrome or not.The function Reverse_Integer is used for checking. If a number remains same, even if we reverse its digits then the number is known as palindrome number. Read the number or letter. So, the number and the given string is called Palindrome. Here, the user is asked to enter an integer. Example: Check Palindrome Number #include using namespace std; int main() { int n, num, digit, rev = 0; cout << "Enter a positive number: "; cin >> num; n = num; do { digit = num % 10; rev = (rev * 10) + digit; num = num / 10; } while (num != 0); cout << " The reverse of the number is: " << rev << endl; if (n == rev) cout << " The number is a palindrome. Palindrome Program using while loop; Palindrome Program using in-built function; Let’s begin. The main () function calls the checkpalindrome (char *s) by passing the string as an argument. Step by step descriptive logic to check palindrome number. 5. In this program we will put some string in the function then the program will check whether the string is Palindrome or not. In the above examples, we can observe that if we reverse the number 121 and string madam we will get the same number and string. Else print, "this string/number is not a palindrome." What is Palindrome number? What is a Palindrome Number? Process returned 0. For example: 121, 12321, 1001 etc. If both letters or numbers are the same, print "this string/number is a palindrome." A palindrome number is a number that is equal to its reverse. This is because the value of num is 0 by now. If you miss this statement, then after completing the first line, it terminates. C++ program to check palindrome number In this example, you are going to learn about C++ program to check palindrome number using the while loop and if statement. Using loop; Using recursion; Checking a string is palindrome or not. Store it in some variable say num. In above program when the user enters the number, the program first reverse the number and then check whether the number is palindrome or not. Find reverse of the given number. Then, the program will print all the palindrome numbers between minimum and maximum number. Explanation : We are using the same array of strings as the above example. C Program – Generating palindrome numbers in a given range ... C Program to reverse a given number using Recursive function; C Program to concatenate two strings without using strcat; Selection Sort Program in C; C Program to Convert Octal Number to Binary Number; Leave a Reply Cancel reply. If the reversedN is equal to originalN then the given number is Palindrome otherwise, the number is not Palindrome. "; return 0; } The same thing can be done without using strlen() function. 2) c=0,calculate the string length n using strlen (s) library function. ANALYSIS. This is the program to check an integer number is a palindrome or not?. Otherwise, it is not a Palindrome number in C programming. We will write the C++ program to check for both number and string. A palindrome is nothing but any number or a string which remains unaltered when reversed. Here we will write a C program to check the palindrome string. In recursion the function calls itself again and again.In above program while executing when the compiler will reach to the Reverse_Integer, then the compiler will jump to Reverse_Integer function. Let’s discuss all the ways one by one. If(Number>0) checks whether the number is 0 or not.It is essential to declare before recursive function otherwise the program will start executing infinite number of times. In this program we will use for loop instead of while loop. Examples: Input: 123 Output: No Input: 585 Output: Yes Approach: Since the number is entered as Command line Argument, there is no need for a dedicated input line; Extract the input number from the command line argument Palindrome number is such number which when reversed is equal to the original number. int rev=0,val; val = num; while(num > 0) { rev = rev * 10 + num % 10; num = num / 10; } After this, the value of rev is compared to val and not num. In this program we will ask user to input a number which user wants to check whether the given number is palindrome or not. For example 12321 is a palindrome number because it remains same if we reverse its digits. This is the program to check an integer number is a palindrome or not? Today we will learn the Palindrome program in C and Palindrome String program in C.So, Before start learning, you should have knowledge of palindrome. Let’s take one more example specifically using a while loop that will also explain the algorithm we discussed in the introduction. If the reverse of the string is the same string then the string is called palindrome. In this program we will use function to check whether the entered number is Palindrome or not.The function … For this we can use strlen() function defined under . The program asks us to use the two functions bool isPalindrom(int number) and int reverse(int number). Should I have reverse return the numbers flipped self (m) then in palindrom compare number … "; else cout << " The number is not a palindrome. A palindrome is a case where if the reverse of any number will be matched correctly with its original integer number, It will be a palindrome. Given a number, the task is to check if this number is Palindrome or not using Command Line Arguments.. 123 = 321 So, 123 is not a palindrome number. In this article we have shared two C programs to check if the input number is palindrome or not. Here is the source code of the C program to check number is palindrome or not using Recursion.
