C/C++ C++ Vector Resize: Counting Down to the Test

[ineedhelpnow]

going through problems to study for a test

Resize vector countDown to have newSize elements. Populate the vector with integers newSize down to 1. Ex: If newSize = 3, then countDown = {3, 2, 1}, and the sample program outputs:

3 2 1 Go!
Sample program:

#include <iostream>
#include <vector>
using namespace std;

int main() {
   vector<int> countDown(0); 
   int newSize = 0;             
   int i = 0;                         

   newSize = 3;
   <STUDENT CODE>

   for (i = 0; i < newSize; ++i) {
      cout << countDown.at(i) << " ";
   }
   cout << "Go!" << endl;

   return 0;
}

i tried countDown.resize(newSize); but it didnt work.

i tried countDown.resize(newSize); but it didnt work.

Hi! ;)

That should work to resize the vector.
But I think you still have to populate the vector in order to get 3, 2, 1. (Thinking)
