Erasing a Space in a String
I am trying to erase a space in a string.
First Name is a private member variable so that is why I used an accessor function. Is something wrong with the following call? I keep on getting errors...
add.getFirstName().erase(add.getFirstName().begin, 1);

If getFirstName() returns a copy, you're only erasing it from the copy - you need to store the copy erase the space, and then setFirstName() to the modified string.

Could you post the code for your class?
Well if the OP is calling the function correctly, getFirstName() would return a reference to itself and then call erase so I don't believe it is returning a copy.
But this is all speculation without actually seeing the class's code.

Ohh ok I see what you are saying now didn't really understand the OP at first sorry about that.
But we will still need a bit more information and the code to be able to tell you exactly what is going wrong. But LB is right you are most likely trying to alter a copy instead of the actual thing.
