C++ Get Variable Name from Document Name

[jmadero]

Hi All,

How would I go about defining a variable from a document name. Example:

document01.doc

I want to take the 01 and set X to equal integer 1. Thanks all

As you already know the extension, you begin by stripping ".doc" from the string.
Then you look, one character at a time, from the right side at each character.
You check each character whether it is a digit (isdigit) and stop if it is not.

This way you know there are two consecutive digits in this string. You strip the rest and transform the string to a integer number with atoi.
