void main()

{

int first,last,flag=1;

char str[100];

clrscr();

printf("Enter number to get to check wheather palindrome or not");

gets(str);

first=0;

last=strlen(str)-1;

printf("%d",first);

printf("%d",last);

while(first<=last)

{

if(str[first]!=str[last])

flag=0;

first++;

last--;

}

if(flag==1)

{

clrscr();

printf("this is palindrome");

getch();

}

else

{

clrscr();

printf("sorry this is not a palindrome");

getch();

}
