1. find lines in a file that contained the word "abracadabra"? 2. encode words in a file, by changing some letters to numbers: a -> 4 o -> 0 (oh to zero) I -> 1 e -> 3 z -> 2 s -> 5 3. print a file on the printer - what command would you use (it won't work on our computer, since it is in a county office, and can't connect to the printer in our lab)? 4. list only the third and fifth field of each line in a file, when the fields are separated by a pipe symbol ("|") 5. Try looking up the following accounts in /etc/passwd. Make sure you find only the account asked for, and no others. kwan kwan1 hale bryan isaacs (What command would you use to do this, and how would you use it?)

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.)
