Palindrome in c without using string function




#include<stdio.h>

int main(){
  char str[100];
  int i=0,j=-1,flag=0;

  printf("Enter a string: ");
  scanf("%s",str);

  while(str[++j]!='\0');
  j--;

  while(i<j)
      if(str[i++] != str[j--]){
           flag=1;
           break;
      }
     

  if(flag == 0)
      printf("The string is a palindrome");
  else
      printf("The string is not a palindrome");

  return 0;
}

What's wrong with this program???


#include
#include
int main()
{
char str[15],rev[15];
int len,i,j;
printf("Enter the string to be checked:");
scanf("%s",str);
len=strlen(str);
j=len-1;
for(i=0;i<len;i++)
{
rev[j]=str[i];
j--;
}
printf("%s\n%s\n%d\n",str,rev,len);
if(strcmp(str,rev))
printf("String is not PALINDROME!\n");
else
printf("String is Palindrome!\n");
}
