I know variable length arrays are not allowed in c++. My code is currently as follows:

int main(){
  int t;
  cin >> t;
  double h[t];
}

How can I create an array with length t then?

Edit: the assignment only allows char, bool, int and double. Vector isn't allowed. When I tried to compile it, it says ISO C++ forbids variable length array 'h'.

    Use std::vector<double> h(t);. (And, don't forget to #include <vector> before.) Commented Mar 11, 2021 at 17:07

    If you can't use vector, then search about new[]. Commented Mar 11, 2021 at 17:10

    An alternative would be to use double *h = new double[t];. (A proper program should delete[] h; after you don't need h anymore.) Commented Mar 11, 2021 at 17:10
