A Palindrome is a word that is the same reading forward or backward. For example, each of the

following words is a palindrome: Madam, Civic, Level. Noon, Refer, Wow. Note that the words are not

case-sensitive.

Write a C program that

Declare an array of twenty characters.

In a loop, get single characters from the user and store them in the array.

After user ends the inputs, check that the characters entered by the user creates a palindrome or

not and provide proper message like the sample execution provided.

Note: In this program, you are not allowed to use pointers and String functions. The only standard

functions you can use are toupper() and tolower() from the ctype library to convert a single character to

its corresponding uppercase or lowercase letters, respectively.

Sample Execution 1:

Enter a word as single characters:

Enter the EOF character to end the input.

Madam

Madam is a Palindrome.

Sample Execution 2:

Enter a word as single characters:

Enter the EOF character to end the input.

Adam

Adam is not a Palindrome.

Sample Execution 3:

Enter a word as single characters:

Enter the EOF character to end the input.

S
