Retail products are identified by their Universal Product Codes (UPCs). The most commonform of a UPC has 12 decimal digits: The
Dahasolnce [82]

Answer:

#include <iostream>

#include <cmath>

using namespace std;

int main(){

   string upc;

   char last;

   cout<< "Enter UPC number: ";

   cin >> upc;

   if (upc.size() == 12){

       last = upc[-1];

   } else{

       return 0;

   }

   cout<< last;

   char myArr[upc.length()];

   for (int i = 0 ; i < upc.substr(0,11).length(); ++i){

       if (upc[i]%2 != 0){

           myArr[i] = upc[i] * 3;

       }

       else{

           myArr[i] = upc[i];

       }

   }

   int sum = 0;

   for (int x = 0; x < sizeof(myArr); ++x){

       sum += (int)myArr[x] - '0';

   }

   if (sum% 10 == last){

       cout<<"UPC number is valid";

   }

   else{

       cout<<"Invalid UPC number.";

   }

}

Explanation:

The UPC number in the c++ source code input must be 12 digits long for the rest of the code to execute.  The code checks the validity of the number by comparing the reminder of the sum division with the last digit in the UPC number.

Briefly explain the benefits and consequences of technology. //PLEASE ANSWER//
Wittaler [7]

Answer:

advantages and disadvantages of technology

Explanation:

Advantages of technology

First, the evolution of technology is beneficial to humans for several reasons. At the medical level, technology can help treat more sick people and consequently save many lives and combat very harmful viruses and bacteria.

The invention of the computer was a very important point. Communication is thus enhanced, and companies can communicate more easily with foreign countries. Research is also simplified.

For companies, progress in implementing strategic technology trends is helping them save time and therefore, money. Exchanges are faster especially with the internet. Sales and purchases are now facilitated and possible worldwide. This allows businesses to buy raw materials with discounts or at reduced prices. Similarly, global tourism has grown.

Technology has also increased the productivity of almost every industry in the world. Thanks to technology, we can even pay with bitcoins instead of using banks. The digital coin has been such a game changing factor, that many realised that this is the right time to open a bitcoin demo account.

When observed more closely, new things are discovered every day. Let’s take for instance when radio waves were discovered, radio broadcasts followed suit almost immediately. The same applies to the television and electricity. If no one had discovered that electricity could be generated, then the entertainment industry wouldn’t be at it’s current stage of development.

Technology improves daily lives; allowing to move physical storage units to virtual storage banks and more. Scientists of the time are also able to send astronauts to the moon thanks to technology.

In the modern industrial world, machines carry out most of the agricultural and industrial work and as a result, workers produce much more goods than a century ago and work less. They have more time to exercise and work in safer environments.

Disadvantages and risks of technology

On the other hand, the evolution of modern technology has disadvantages, for example, dependence on new technology. Man no longer needs to think. Even if the calculator is a good invention, man no longer makes mental calculation and no longer works his memory. The decline of human capital implies an increase in unemployment. In some areas, devices can replace the human mind.

The use of technology certainly needs rule and new laws. For example internet use is an individual freedom. However, the invention of the atomic bomb cannot be an individual freedom. In fact, regulations are difficult to implement when these technologies are introduced – such as regulation surrounding the impending arrival of autonomous vehicles.

Finally, as most technological discoveries aim to reduce human effort, it would imply that more work is done by machines. This equates to less work for people: the human is becoming ever so obsolete by the day, as processes become automated and jobs are made redundant.
