Answers:
What is the index of the last element in the array? stArr1.length()-1
This prints the names in order. How would I print every other value? Change line 4 to: index = index +2
Change line 7 to: i < names.length
Answer:
// here is code in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
int n;
double average,sum=0,x;
cout<<"enter the Value of N:";
// read the value of N
cin>>n;
cout<<"enter "<<n<<" Numbers:";
// read n Numbers
for(int a=0;a<n;a++)
{
cin>>x;
// calculate total sum of all numbers
sum=sum+x;
}
// calculate average
average=sum/n;
// print average
cout<<"average of "<<n<<" Numbers is: "<<average<<endl;
return 0;
}
Explanation:
Read the total number from user i.e "n".Then read "n" numbers from user with for loop and sum them all.Find there average by dividing the sum with n.And print the average.
Output:
enter the Value of N:5
enter 5 Numbers:20.5 19.7 21.3 18.6 22.1
average of 5 Numbers is: 20.44

Answer:
True
Explanation:
While I believe it's a compendium of the both(both true and false), I when asked to pick just one, I would go with yes. They're are lots of things we humans do on a general note that causes flooding. Although, heavy rainfall can also cause flooding and that's not as a result of human activity, but directly. But then, activities like not maintaining a dam, or erecting a structurally failed dam can cause flood to occur at any point in time, without warning even. Another way is when due to our activities, we block the rivers, this can also lead to flooding exactly like the case of heavy rainfall does. Lack of good drainage facilities, drainage wouldn't create itself, we as humans do. When we don't were essentially creating an excuse for an eventual happening of flood.
Succinctly put, human activities also cause floods, as much as natural events causes flood.
