Answers for "palindrome string logic in c"

check is number is palindrome in C

#include <stdio.h>
#include <conio.h>

void main()
{

    int n,i,r=0;
    
    printf("Enter a number: ");
    scanf("%d",&n);
    
    for(i=n;i!=0;i)
    {
        r=r*10;
        r=r+ i%10;
        i=i/10;
    }
    
    if(r==n)
        printf("palindrome");
    else
        printf("Not palindrome");
}

palindrome string program in c

#include <stdio.h>
#include <string.h>
int main()
{

     char str[80];
     int length;
     printf("\nEnter a string to check if it's a palindrome: ");
     scanf("%s", str);     // string input
     length = strlen(str); // finding the string length
     int i, j, count;
     for (i = 0, j = length - 1, count = 0; i < length; i++, j--)
     {
          // matching string first character with the string last character
          if (str[i] == str[j])
          {
               count++; // if character match, increasing count by one.
          }
     }
     if (count == length) // if count == length, then the string is a palindrome.
     {
          printf("'%s' is a palindrome.\n", str);
     }
     else // otherwise the string is not a palindrome.
     {
          printf("'%s' is not a palindrome.\n", str);
     }
     return 0;
}
