Hello I am a beginner in programming. Can anyone give me an idea on how to do this?

I will be using an edit box to input space-separated numerical values. Then the input values will then be stored in an array of type double.

For example:
Input values to the edit box are: 1.1 2.2 3.3

Input values will be stored in the array in the following manner:
arrayNum[0] = 1.1
arrayNum[1] = 2.2
arrayNum[2] = 3.3

Thanks.
