Using Cygwin and gcc$,$ create a C program that reads a $($potentially$)$ multi$-$word message from the keyboard and checks whether or not it's a palindrome $($i$.$e$.$ the letters in the message are the same from left to right as from right to left$).$ Whitespace and punctuation should be ignored in the palindrome check.$$ The check should also be case$-$agnostic $($i$.$e$.$ don't distinguish between upper$-$ and lowercase$).$

Implement your program WITHOUT using any array indexing.$$ Rather, use pointers to keep track of positions within the array.$$ The only place square brackets should be used is in your array declaration.$1$ point will be deducted from your score for each additional use of square brackets.

Assume that input from the keyboard will not exceed $200$ characters.

Submit a $.$c file.

Remember the $80-$character line limit$.$

Remember the function header for each function you write.

$$

Example Program $1$:

Enter a word$/$phrase: Madam, I$\text{'}$m Adam.

The word$/$phrase is a palindrome.
