No thanks.

lol

OK, done. Now what?

Why ?

#include<stdio.h>
#include<string.h>
#define size 25

void main()
{
char strsrc[size];
char strtmp[size];

clrscr();
printf("\n Enter String:= "); gets(strsrc);

strcpy(strtmp,strsrc);
strrev(strtmp);

if(strcmp(strsrc,strtmp)==0)
printf("\n Entered string \"%s\" is palindrome",strsrc);
else
printf("\n Entered string \"%s\" is not
palindrome",strsrc);
getch();
}

And now try compiling this on something that isn't outdated and non-standard and see if it compiles....

Furthermore, even dribble like this should be placed in code tags. Learn how to use them.
