Write a program that reads a string of characters, pushing each character onto a stack as it is read and simultaneously adding i
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>.

int n; //to store size of array  

char* ArrayChallenge(int arr[]) //function returns string true or false

{

  int i, j;

  int sum = 0;

  for(i = 0; i < n; i++)

  {

      sum = sum + arr[i]; //count sum

  }  

  for(i = 0; i < n; i++)

  {

      for(j = i+1; j < n; j++) //loop for every two elements in array

      {

          if(arr[i]*arr[j] > 2*sum) //check if proudct of two elements > 2 times sum

          {

              printf("\n%d x %d = %d, 2xSum = %d\n", arr[i], arr[j], arr[i]*arr[j], 2*sum);

              return "true"; //If proudct of two elements > 2 times sum. return true

          }

      }

timofeeve [1]

Hi;

In the question, Robert gives the explanation that there is an error in the BIOS. A BIOS (Standing for Basic Input & Output System) is a ROM chip, and is vital for the computer to initialize devices such as RAM, the CPU, etc. If there is ever an error there, a computer simply cannot boot.

From the options given, your answer given would be C. ROM.

I hope this helps!
