Check the given number is palindrome number or not using c program
Code 1:
1. Wap to check a number is palindrome
2. C program to find whether a number is
palindrome or not
#include<stdio.h>
int main(){
int num,r,sum=0,temp;
printf("Enter a
number: ");
scanf("%d",&num);
temp=num;
while(num){
r=num%10;
num=num/10;
sum=sum*10+r;
}
if(temp==sum)
printf("%d is a palindrome",temp);
else
printf("%d is
not a palindrome",temp);
return 0;
}
Sample output:
Enter a number: 131
131 is a palindrome
Code 2:
1. Write a c program for palindrome
2. C program to find palindrome of a number
3. Palindrome number in c language
#include<stdio.h>
int main(){
int num,r,sum,temp;
int min,max;
printf("Enter
the minimum range: ");
scanf("%d",&min);
printf("Enter
the maximum range: ");
scanf("%d",&max);
printf("Palindrome
numbers in given range are: ");
for(num=min;num<=max;num++){
temp=num;
sum=0;
while(temp){
r=temp%10;
temp=temp/10;
sum=sum*10+r;
}
if(num==sum)
printf("%d
",num);
}
return 0;
}
Sample output:
Enter the minimum range: 1
Enter the maximum range: 50
Palindrome numbers in given range
are: 1 2 3 4 5 6 7 8 9 11 22 33 44
Code 3:
1. How to check if a number is a palindrome using for loop
#include<stdio.h>
int main(){
int num,r,sum=0,temp;
printf("Enter a
number: ");
scanf("%d",&num);
for(temp=num;num!=0;num=num/10){
r=num%10;
sum=sum*10+r;
}
if(temp==sum)
printf("%d is a
palindrome",temp);
else
printf("%d is
not a palindrome",temp);
return 0;
}
Sample output:
Enter a number: 1221
1221 is a palindrome
Code 4:
1. C program to check if a number is palindrome using recursion
#include<stdio.h>
int
checkPalindrome(int);
int main(){
int num,sum;
printf("Enter a
number: ");
scanf("%d",&num);
sum
= checkPalindrome(num);
if(num==sum)
printf("%d is a palindrome",num);
else
printf("%d is
not a palindrome",num);
return 0;
}
int checkPalindrome(int num){
static int sum=0,r;
if(num!=0){
r=num%10;
sum=sum*10+r;
checkPalindrome(num/10);
}
return sum;
}
Sample output:
Enter a number: 25
25 is not a palindrome
