Write a c program to check given string is palindrome number or not



#include<string.h>
#include<stdio.h>
int main(){
  char *str,*rev;
  int i,j;
  printf("\nEnter a string:");
  scanf("%s",str);
  for(i=strlen(str)-1,j=0;i>=0;i--,j++)
      rev[j]=str[i];
      rev[j]='\0';
  if(strcmp(rev,str))
      printf("\nThe string is not a palindrome");
  else
      printf("\nThe string is a palindrome");
  return 0;
}



Definition of Palindrome string:

A string is called palindrome if it symmetric. In other word a string is called palindrome if string remains same if its characters are reversed. For example: asdsa
If we will reverse it will remain same i.e. asdsa

Example of string palindrome:  a,b, aa,aba,qwertrewq etc.
