Sense Eddie clicked the undo command he wouldn't want to click it again, if he does more words will leave. Sense he did not copy the word, he cannot paste it. And if he would press Undo twice, then that would take him back further, so what he wants to do is click the redo command.
Hope this helps.

A computer has ideas from a bunch of different people instead of the knowledge of just one person.
Answer:
Naphtha is used to dilute heavy crude oil to reduce its viscosity and enable/facilitate transport; undiluted heavy crude cannot normally be transported by pipeline, and may also be difficult to pump onto oil tankers. Other common dilutants include natural-gas condensate, and light crude.
Answer:
#include <iostream>
#include<cmath>
using namespace std;
int main()
{
double total = 0;
double check=1;
double ct=0;
double old=1;
while( fabs(total - old) > 0.00005 )
{
old=total;
total=total+check*4.0/(2.0*ct+1);
ct=ct+1;
check=0.0-check;
}
cout<<"Approximate value of pi is "<<total<<endl;
return 0;
}
Explanation:
- Initialize all the necessary variables.
- Run a while loop until the following condition is met.
fabs(total - old) > 0.00005
- Inside the while loop calculate the total value.
- Lastly, display the approximate value of pi.
