It has to allocate a new ansistring.
Another question: if I do "s += c” will the string reallocate memory for 1
character or is there an exponential growing function? If it does grow by one
character at a time how can I reserve a certain capacity in advance?
An exponential growing function applied to all strings would have many
worse case behaviours, where it would eat up heaps of memory for
nothing. This is why it is better to have the programmer indicate it is
a growing string some how (or have a separate type, like TStringBuilder
mentioned by Jonas)
