How to add value to each field which have field name like 'A1' , 'A2' , 'A3' using for loop

Hi,

Could you guys help me about this?
I'm newbie for programming.
I want to add value from my List to my custom fields which have sequential number as suffix of each field by using for loop.

Similar this..
Example
            My custom field API name : A_1__c,A_2__c,A_3__c

            List<User> userList = new List<User>();
            Integer counterXX = 1;
            for(User rUser : userList){
                xxx.A_counterXX__c = rUser.Id;
                counterXX++;
            }
Can I use this logic or what it should be? Please give me some advices.

Thank you.

You can use the put method on the sObject. Inside the for loop you can do something like this:
xxx.put('A_' + counterXX + '__c', rUser.Id);
The first parameter of the method is the field API name in a string format. The second one is the value you want to assign to that field.
