    Obtaining array dimension

    What's the easiest way to obtain an array element from a user and placing it into memory? As a result, I need to read double values and call an already written function to read these values.

    Help?

    1)Obtaining array dimension

    For char arrays:
    strlen() in <cstring>
    char text[] = "Hello world.";
    cout<<strlen(text);

    For strings:
    length() in <string>
    string text;
    cout<<text.length();

    Other arrays:
    sizeof(array_name)/sizeof(array_name[0])

    2)What's the easiest way to obtain an array element from a user and placing it into memory?
    Code:
    double numbers[20];
    
    for(int i=0; i<20; i++)
    {
        cout<<"Enter a floating point number:";
        cin>>numbers[i];
    }
    3)As a result, I need to read double values and call an already written function to read these values.

    some_function(numbers);
