I used the vector to solve this problem, but the system told me "Crash".
I want to know why, so sent help to you, thank you.

Below is my solution:
#include <iostream>
#include <vector>
#include <math.h>
using namespace std;

int main()
{
    vector<double> doubleVector;
    int i = 0;
    double cinVector = 0;

    // Read in numbers
    while (cin >> cinVector)
    {
        doubleVector.push_back(cinVector);
        i++;
    }

    // Display the results
    while (i > 0)
    {
        cout << sqrt(doubleVector.at(i)) << endl;
        i--;
    }

    return 0;

}




In addition, what will cause the "Crash"?

Input: n numbers

After 1st while cycle: i = n

doubleVector.at(i) - crash because size = n and only doubleVector[n-1] exists.

And you should print numbers with 4 digits after the decimal point.
