Acustomer reports that recently several files cannot be accessed. the service technician decides to check the hard disk status and the file system structure. the technician asks the customer if a backup has been performed on the disk and the customer replies that the backup was done a week ago to a different logical partition on the disk. what should the technician do before performing diagnostic procedures on the disk? a. run the chkdsk utility. b. back up the user data to a removable drive. c. perform file restore from the existing backup copy at the logical partition. d. install a new hard disk as the primary disk, then make the current disk a slave.

All of the following are characteristics that must be contained in any knowledge representation scheme except

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.)
