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…

Cryptology is the science of making and breaking codes. This lab explores how the idea or functions and their inverses can be used to encode and decode messages. To encode and decode a message, first replace each letter of the alphabet with a positive integer using the following scheme, thus rewriting the original message as numbers instead of words: P- 16 Q- 17 R- 18 S- 19 T-20 Z-26 Blank - 27 A – 1 В - 2 С -3 D- 4 E- 5 F- 6 G- 7 H-8 |- 9 J- 10 K- 11 L-12 М -13 N- 14 O- 15 U- 21 V- 22 W-23 X-24 Y-25 ENCODING: A one-to-one function can be used to encode a numerical message. For example, suppose you want to send the message MATH to a friend, and you have decided that the function f(x) = 3x + 4 will be the encoding function, This function simply describes the procedure used to create the encoded message – in this case multiply by 3 and add 4.

I know that it is technically undefined (or, at the very least, ambiguous), but sometimes we consider the value to be zero and other times to be infinity, which are, obviously, diametrically different (apart from negative numbers). I'm not so much interested in the nature of division by zero but more in how we determine whether we regard the value as zero or infinity? Again, this is in the context of electronics and circuit analysis, to be more specific.
