Thread: Size of Array, user inputted..

If you really want to go the dynamic memory allocation route then you've got some switching around of code to do to get it working properly:

Code:

#include <iostream>
#include <string>
#include <algorithm>

int main()
{
    int length;

    std::cout << "How many numbers do you wish to input?: ";
    std::cin >> length;    // Get length from user "before" you attempt to allocate space

    // Now allocate space based on user input length...
    int * list = new int[length];

   
    // Do whatever you need to with the list array you've allocated.


    // Clean up the memory you've allocated.
    delete [] list;

    return 0;
}

Using a vector is far better like others have mentioned... you don't need to new/delete any memory, it's automatically done for you by the vector itself.

The algorithm header you are including contains a templated function that can easily do the counting for you (not gonna tell you what it's called) although I suspect you need to learn/experience loops more.
