Jack has a fear of getting up in front of a group of people and giving a presentation. When he gave his last presentation, he talked quickly, which made it hard for people to understand him. What constructive criticism could you give Jack?

You did an amazing job on the research. When I present, I find it helpful to take a deep breath. It helps me relax and slow down, which helps my audience.
You do not have confidence in your ability, and it shows. You need to get training on presenting.
You had a lot of great points in your presentation. Everyone walked away understanding what you were saying.
You need to slow down. People do not like it when you talk so fast.

Consider the following function main: int main() { int alpha[20]; int beta[20]; int matrix[10][4]; . . } a. write the definition of the function inputarray that prompts the user to input 20 numbers and stores the numbers into alpha. b. write the definition of the function doublearray that initializes the elements of beta to two times the corresponding elements in alpha. make sure that you prevent the function from modifying the elements of alpha. c. write the definition of the function copyalphabeta that stores alpha into the first five rows of matrix and beta into the last five rows of matrix. make sure that you prevent the function from modifying the elements of alpha and beta. d. write the definition of the function printarray that prints any onedimensional array of type int. print 15 elements per line. e. write a c11 program that tests the function main and the functions discussed in parts a through d. (add additional functions, such as printing a two-dimensional array, as needed.)
