Write a program that takes a value x as input and outputs this sum for n taken to be each of the values 1 to 100. The program should also output ex calculated using the predefined function exp. The function exp is a predefined function such that exp(x) returns an approximation to the value ex. The function expis in the library with the header file cmath. Your program should repeat the calculation for new values of x until the user says she or he is through. Use variables of type double to store the factorials or you are likely to produce integer overflow (or arrange your calculation to avoid any direct calculation of factorials). 100 lines of output might not fit comfortably on your screen. Output the 100 output values in a format that will fit all 100 values on the screen. For example, you might output 10 lines with 10 values on each line.

The idea that, for each pair of devices v and w, there’s a strict dichotomy between being “in range” or “out of range” is a simplified abstraction. more accurately, there’s a power decay function f (·) that specifies, for a pair of devices at distance δ, the signal strength f(δ) that they’ll be able to achieve on their wireless connection. (we’ll assume that f (δ) decreases with increasing δ.) we might want to build this into our notion of back-up sets as follows: among the k devices in the back-up set of v, there should be at least one that can be reached with very high signal strength, at least one other that can be reached with moderately high signal strength, and so forth. more concretely, we have values p1 ≥ p2 ≥ . . ≥ pk, so that if the back-up set for v consists of devices at distances d1≤d2≤≤dk,thenweshouldhavef(dj)≥pj foreachj. give an algorithm that determines whether it is possible to choose a back-up set for each device subject to this more detailed condition, still requiring that no device should appear in the back-up set of more than b other devices. again, the algorithm should output the back-up sets themselves, provided they can be found.\

You will subnet the network address 172.31.103.0/24. the network has the following requirements: · room-114 lan will require 27 host ip addresses · room-279 lan will require 25 host ip addresses · room-312 lan will require 14 host ip addresses · room-407 lan will require 8 host ip addresses how many subnets are needed in the network topology?
