Answer:

The total const is 13025 KWh

Explanation:

These are the steps to solve this problem:

  1. Convert all the powers from W to KW dividing by 1000.
  2. Convert all the times on minutes to hours dividing by 60.
  3. Then you can apply energy consumption formula Energy = Power*Time for any of the appliances. the results will be at KWh.
  4. Sum all the consumtions and you will have the total cost.

Attached you will have a spreadsheet as a guidance. Any  questions, just let me know.

sleet_krkn [62]

Answer:

#include <iostream>

#include <stack>

#include <queue>

#include <string>

int main()

{

   while ( true )

   {

       std::string letters;

       std::cout << "Please enter a word (Enter - exit): ";

       std::getline( std::cin, letters );

       if ( letters.empty() ) break;

       std::stack<char>

           s( std::stack<char>::container_type( letters.begin(), letters.end() ) );

       std::queue<char>

           q( std::queue<char>::container_type( letters.begin(), letters.end() ) );

       while ( !s.empty() && s.top() == q.front() )

       {

           s.pop();

           q.pop();

       }

if ( s.empty() ) std::cout << "The word is a palindrome" << std::endl;

       else std::cout << "The word is not a palindrome" << std::endl;

   }

   return 0;

}

Explanation:

A <em>stack</em> is used to replicate a stack data structure in C++  while <em>Queue </em>container is a replica of the queue data structure in C++, Unlike stack, in the queue container, there are two ends, i.e. front, and back.

In the code above to be able to use used stack and queue, we included the headers #include <stack> and#include <queue>.
