ARRAY:
An array is defined as a group of related data items stored by means of a single variable name.

STRUCTURE:
Structure is defined as a data type to represent several different types of data with a single name.

DIFFERENCE BETWEEN ARRAYS AND STRUCTURES:
1.All data in a array should be of same data type.But in structures data can be of different data types.
2.Individual entries in an array are called elements.But in structure individual entries are called members.

using only #include and #include Write a program in C that will read an input from the user and print it back to the user if it is a palindrome. The string ends when it encounters a whitespace. The input string is at most 30 characters. Assume the string has no spaces and distinguish between and lowercase. So madam is a palindrome, but MadAm is not a palindrome. Use scanf and %s to read the string. Sample Test: Enter a string: madam madam is a palindrome. Enter a string: 09023 09023 is not a palindrome.
