Create a function that reads (by reading the dimension first and then the elements) and prints an array of integers. Read the dimension n from the keyboard. Using the function just created read 2 arrays a and b from the keyboard with the same dimension (one array first then the other). Next create a function that calculates the array sum, where each elements of sum is the sum of the corresponding elements from the 2 initial arrays:

Example:

If the first array is: 2 -1 0 8

The second array is: 0 5 0 -1

The result array is: 2 4 0 7

Read an array of chars (string; word or line from the screen). Extract and display each letter that have as position the number in the aray result; position numbering (index) in any array (the strinf is an array of chars) start from 0.

Example:

If the string is "SuperFunecstatic"

We extract the letters with the positions 2 4 0 7

the extracted letters are: p r s n

If the number for the position is negative or is bigger than the length of the string then display X for the extracted letter. (C programming)
