What you want to do isn't a built in feature. You want to combine or concatenate the value of two different fields to create the value of a third field. This can only be done using custom PHP and available hooks.
You would add a Hidden Field to your form to use to store the value of Field C. You would then use custom PHP you add to your themes functions.php that uses the gform_pre_submission hook to get the values of Field A and Field B and combine them and store them as the value of Field C (the hidden field you added to your form).
Here is a support forum thread that discusses how to do this. Check out the reply by Alex that includes sample code:

You would have to customize the code to suit your specific use case and needs.
