where summation is from i=1 to 10.

Write a program using a 1D array to evaluate the following expressions: Total = ∑ (Xi) 2 where summation is from i=1 to 10.

Write a function isPalindrom() that takes as input a C string and its size, and recursively tests whether it is a palindrome (a word or phrase which remains the same if reversed. e.g. radar, kayak etc). The function returns the Boolean data type which is either true or false. The required header “stdbool.h” has already been included in tasks.h.

The function has the following prototype:

bool isPalindrom(char * ptr_array, int size);

The recursive definition of a palindrome is:

• The string is a palindrome if it has only one character or is an empty string.

• The string is a palindrome if the first and the last characters are the same and the characters in between form a palindrome.

Write a C Program that does the following:

1. Declares a C-String called ‘m1’ and initializes it with the text “Programming is great fun!”.

2. Uses C-function puts() to print this string.

3. Asks the user to enter a string named ‘m2’ (Hint: Use gets() function for this.)

4. Concatenates the two strings and stores the result in ‘m3’.

For example, if the user enters m2 as “Not Really!”, m3 should be “Programming is great fun! Not really!”

5. Inserts the user entered array (m2) into m1 after “Programming is ...”

For the above example, the resultant String would become “Programming is Not really! great fun!”
