How to cin to a vector

I\'m trying to ask the user to enter numbers that are put into a vector, then using a function call to count the numbers, why is this not working? I am only able to count t

Answer 1

In this case your while loop will look like

int i = 0;
int a = 0;
while (i < n){
  cin >> a;
  V.push_back(a);
  ++i;
}
