Write a C program to read the values of a 6 x 6 2D array from a file, and then produce an output file that contains the transpose of the array. Array values are decimal. The input and output files contain one array row on each text line. a.)Extend the previous exercise to count the total number of duplicate elements in the 2D array. b.) Extend the program in exercise 1 to count the frequency of each element of the 2D array. c.)Extend the program in quesyion1 to separate the positive and negative values of the 2D array in two separate 1D arrays. Save the two 1D arrays in an output text file.

Local area networks use many of the same network technologies and the internet, only on a smaller scale. devices that access lans are equipped with a network interface that contains circuitry for wireless or wired connections. devices also have a physical address, in addition to the ip addresses acquired from a dhcp server. the most popular wired technology is . the most popular wireless technology is , which can be configured as a(n) or star topology. setting up a lan and configuring its router is fairly easy. the first step is to change the standard to one that is secure. next, create a(n) that uniquely identifies the network by name. it is also important to activate wireless to prevent wireless signals from being intercepted during transmission. a limited-access network can be created for visitors to use. by activating , the router will be able to assign ip addresses to each device that joins the network. to connect to a secure lan that is protected by encryption, an encryption , or password, is required. lans can be used to access data collected by iot devices and the networks that tie these devices together. technologies such as rfid, nfc, bluetooth smart, zigbee, and z-wave offer -power links, essential for battery-powered devices that can’t expend excess amounts of energy transmitting data.
