Question

My program in C which is Palindrome has an error in its function. My function is not comparing the 2 characters in my string. When I type a single character it answers palindrome but if it is two or more always not palindrome.

Code:

          int IntStrlength=strlen(StrWord);
          int IntCtr2=0;
          int IntCtr=1, IntAnswer;
          while(IntCtr<=(IntStrlength/2)){
                printf(" %d %d\n", IntCtr2,IntStrlength);
               if(StrWord[IntStrlength] != StrWord[IntCtr2]){
                  IntAnswer=0;
                  printf(" %d=Not Palindrome", IntAnswer);
                  exit (0);
                 }//if(StrWord[IntCtr2]!=StrWord[IntStrlength]) <---------
               else{
                  IntCtr2++;
                  IntStrlength--;
                  }// else <--------
               IntCtr++;
          }//while(IntCtr<IntStrlength/2) <-----------
          IntAnswer=1;
          printf(" %d=Palindrome", IntAnswer);
          return ;

This may works for you

 #include <stdio.h>
    #include <stdlib.h>
    
    int main(void) {
        setbuf(stdout,NULL);
        int i,limit;
        char string1[10];
        int flag=0;
    
    
        printf("enter a string");
        scanf("%s",string1);
        limit=strlen(string1);
        for(i=0;i<limit;i++){
            if(string1[i]!=string1[limit-i-1]){
                flag=1;
                break;
            }
    
        }   if(flag==1){
            printf("entered string is not  palindrome");
        }else{
            printf("entered string is  palindrome");
        }
    
    
    
    
        return EXIT_SUCCESS;
    }

Answer 8

I have solution for this    
char a[]="abbba";
int i,j,b=strlen(a),flag=0;
          for(i=0,j=0; i<b; i++,j++)
          {
              if(a[i]!=a[b-j-1])
              {
               flag=1;
               break;
              } 
          }
        if(flag)
        {

                      printf("the string is not palindrum");
        }
        else
              {
                      printf("the string is  palindrum");
        }

You can visit my github link for the code. You can download the code from there. I guess it will help you to understand the code. Code contains many comments you can remove and experiment with it. Palindrome number If something is missing please let me know. If you like the code and explanation upvote my comment. To understand the code and run it in your system visit the link (Palindrome Code), download the code and play with it.
