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.
Answer:
10 or 22 or 15 or 40
Explanation:
In the second for loop[for (int k = 1; k < arr[0].length; k++)], k starts from 1 instead of zero. That means that it doesn't read the first value of every row when finding num.
So if num was any of the above values, the program wouldn't work. I had the same question, and the answer for mine was 15.
Answer:War driving
Explanation: War driving is the activity which is done for searching for the Wi-Fi connection while driving vehicle .The main purpose of the war driving is gaining and accessing the network of Wi-Fi by being in slowly moving vehicle. The act is carried out by the individual or more people.
Other options are incorrect because Wifi driving and Wifi finding are not technical words in the computer field and E-stalking is the stacking activity with the help of internet enables electronic devices.Thus, the correct option is war driving.
Answer:
a. input={4,4}
b. input={3,6,6}
c. input={7,8,8,4}
d. input={5,7,7,4,4}
e input={4,6,6,7,9,9}
Explanation:
First understanding the method in the method we are iterating over array upto the second last element and in the loop we are checking that the current element is less than then next array element if it is less then we are assigning the value of next element to the current element.So the outputs are stated above according to the method execution.
