Answer:

A. Corrupted or missing display driver

Explanation:

The most likely reason for this problem would be a corrupted or missing display driver. The display driver is in charge of grabbing the information from the graphic card and adjusting all the necessary settings so that all of the graphic card's power is able to be utilized. Missing or corrupt drivers can cause errors such as laggy display, wrong resolution/minimum resolution, missing display settings, etc. A graphic card failure on the other hand would show no image on the screen whatsoever when turning on the computer.

Assume that nextWord is a String variable that has been given a String value consisting entirely of letters. Write some Java cod
wel

Answer:

The code example is given below with explanation in c++ language.

Explanation:

Comments will explain what's going on in the code. Below code is already compiled and tested.

#include <time.h>

#include <iostream>

#include <sstream>

using namespace std;

int main(void)

{

//defining start and end time variable

// which will be used to break the infinte loop

   time_t endwait;

   time_t start = time(NULL);

   time_t seconds = 3; // end loop after this time has elapsed

cout<<"Input your number :";

long userNum;

cin>> userNum;

// initializing end time by adding seconds with start time

   endwait = start + seconds;

   // defining outputString which will concatenate all the  

   // divisible numbers in loop

string outputString="";

// bool isCompleted will use to check whether our  

// loop breaks successfully or time is expired.

bool isCompleted=true;

// iterate loop until it comes to 1. as in loop

// the program already displayed the 1 value.

   while (userNum>1)

   {  

  // checking start and end time comparison to  

  // break the infinite loop after some seconds

    if(start >= endwait){

     cout<< "Program end never reached.";

     isCompleted=false;

     break;

 }

 

    userNum=userNum/2;

   // defining stringstream to convert from long to string

    stringstream longToString;

    longToString<<userNum;

  // concatenating all the values

    outputString = outputString + longToString.str()+" ";

   // re initializing the start time with current time.

       start = time(NULL);

   }

   

  // check if while loop breaks successfully then print the

   // series of numbers here.

   if(isCompleted) {

    cout << outputString;

}

   return 0;

}

IgorC [24]

ONE
