Answer:
I think the answer is going to be records
You are responsible for a rail convoy of goods consisting of several boxcars. You start the train and after a few minutes you realize that some boxcars are overloaded and weigh too heavily on the rails while others are dangerously light. So you decide to stop the train and spread the weight more evenly so that all the boxcars have exactly the same weight (without changing the total weight). For that you write a program which helps you in the distribution of the weight.
Your program should first read the number of cars to be weighed (integer) followed by the weights of the cars (doubles). Then your program should calculate and display how much weight to add or subtract from each car such that every car has the same weight. The total weight of all of the cars should not change. These additions and subtractions of weights should be displayed with one decimal place. You may assume that there are no more than 50 boxcars.
Example 1
In this example, there are 5 boxcars with different weights summing to 110.0. The ouput shows that we are modifying all the boxcars so that they each carry a weight of 22.0 (which makes a total of 110.0 for the entire train). So we remove 18.0 for the first boxcar, we add 10.0 for the second, we add 2.0 for the third, etc.
Input
5
40.0
12.0
20.0
5. 33.

Output
- 18.0
10.0
2.0
17.0
-11.0
Answer:
The program in C++ is as follows:
#include <iostream>
#include <iomanip>
using namespace std;
int main(){
int cars;
cin>>cars;
double weights[cars];
double total = 0;
for(int i = 0; i<cars;i++){
cin>>weights[i];
total+=weights[i]; }
double avg = total/cars;
for(int i = 0; i<cars;i++){
cout<<fixed<<setprecision(1)<<avg-weights[i]<<endl; }
return 0;
}
Explanation:
This declares the number of cars as integers
int cars;
This gets input for the number of cars
cin>>cars;
This declares the weight of the cars as an array of double datatype
double weights[cars];
This initializes the total weights to 0
double total = 0;
This iterates through the number of cars
for(int i = 0; i<cars;i++){
This gets input for each weight
cin>>weights[i];
This adds up the total weight
total+=weights[i]; }
This calculates the average weights
double avg = total/cars;
This iterates through the number of cars
for(int i = 0; i<cars;i++){
This prints how much weight to be added or subtracted
cout<<fixed<<setprecision(1)<<avg-weights[i]<<endl; }

Explanation:
If a system contains 1,000 disk drives, each of which has a 750,000- hour MTBF, which of the following best describes how often a drive failure will occur in that disk farm:
a. once per thousand years
b. once per century, once per decade
c. once per year, once per month
d. once per week
e. once per day
f. once per hour
g. once per minute
h. once per second
Answer:
once per month
Explanation:
The correct answer is - once per month
Reason -
Probability of 1 failure of 1000 hard disk = 750,000/1000 = 750 hrs
So,
750/24 = 31.25 days
⇒ approximately one in a month.
