Task 4 [Computing Pl via Leibniz series] This task is to help you use for-loops for mathematical expressions in code. It is an irrational number - that means it cannot be expressed as a fraction. Ever wonder how we compute ? One of the pioneers of the mechanical calculator, Gottfried Wilhelm von Leibniz, proved that could be expressed with the following infinite series: 1- 1 1 1 5 7 9 11 13 15 17 19 1 1 1 1 1 1 + + 3 We can rewrite Leibniz's series in a more compact form as follows: π = 4 x Notice the alternating plus/minus sign in the series. We call each of the fractions in the series a "term." To compute requires the summing of an infinite number of terms; however, in practice, this is not possible. Instead, we can only approximate the true value using a finite number of terms. Using the Leibniz formula, the more terms we compute in the series, the more accurate our calculation of . Your task is to compute π up to a user-specified number of terms (i.e., up to M terms). Don't get…

A barcode scanner for Universal Product Codes (UPCS) verifies the 12-digit code scanned by comparing the code's largest digit (called a check digit) to its own computation of the check digit from the first 11 digits as follows: 1. Calculate the sum of the digits in the odd-numbered positions (the first, third,. eleventh digits) and multiply this sum by 3. 2. Calculate the sum of the digits in the even-numbered position (the second, fourth...tenth digits) and add this to the previous result. 3. If the last digit of the result from step 2 is 0, then 0 is the check digit. Otherwise, subtract the last digit from 10 to calculate the check digit. 4. If the check digit matches the final digit of the 12-digit UPC, the UPC is assumed correct By using C++ write a program that prompts the user to enter the 12 digits of a barcode separated by space. The program should store the digits in an integer array, calculate the check digit, and compare it to the final barcode digit. If the digits match,…
