How to initialize array using user input?

[hopesfall]

How could I create an array of size n, where n is a int given by the user?

Something like this:

	
int MAX_SIZE;
cout << "Enter size of array: " << endl;
cin >> MAX_SIZE;

int myArray[MAX_SIZE]; // error: expression must have a constant value

return 0;

Better yet, is there anyway to set the value of a const int to n (the number given to me by user) so that I can use it throughout my program?

By using dynamic arrays:

cin >> maxSize;
vector<int> myArray(maxSize);

Sure...

int input;
cout << "Enter size of array: " << endl;
cin >> input;
const int maxSize=input;

But you still can't use maxSize for the dimensions of a regular array, since it must be a compile-time constant.
