Write a C program that is given a file name as a command line argument. Open the file and read it. At the end of the file, print out: LINES: lc WORDS: wc CHARS: cc DIGITS: dc Where lc is the number of lines, wc is the number of words, cc is the number of characters, and dc is the number of digit characters, 0-9. If no file name is provided, the program should use the standard input instead of a file. If the file cannot be opened, print "CANNOT OPEN " followed by a space and the filename, and stop. The program should ignore any extra command line arguments that are provided after the file name.

Ahouse has the following electrical appliance usage (1) single 40w lamp used for 4 hours per day (2) single 60w fan used for 12 hours per day (3) single 200w refrigerator that runs 24 hours per day with compressor run 12 hours and off 12 hours find the solar power inverter size in watt with correction factor of 1.25.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
