char a[100], b[100];

printf("Enter the string to check if it is a palindrome\n");
gets(a);

strcpy(b,a);
strrev(b);

printf("Entered string is a palindrome.\n");
else
printf("Entered string is not a pailndrome.\n");

getch();
return 0;
}

Answer 2

what is the function of strcmp, strrev..?

Answer 3

strcmp (char* str1, char *str2) ---- compares the two string str1, str2
if str1 and str2 are equal, it returns 0, otherwise the difference between the last unequal character of the str1, str2 ===== like *str2 - *str1

strrev(char* str) ---- reverses the presented string (in place) and returns the reversed string
