c++ Programming Glossary: concatenationsTrouble implementing a “rope” data structure in C++ http://stackoverflow.com/questions/12286841/trouble-implementing-a-rope-data-structure-in-c the directory tree. Without this though you get fast concatenations but arbitrary character accesses may unpredictably degenerate.. I guess if it suits your use case you could implement move concatenations this would give possibly constant time addition and you still..
What is the equivalent of CPython string concatenation, in C++? [duplicate] http://stackoverflow.com/questions/13021985/what-is-the-equivalent-of-cpython-string-concatenation-in-c the following optimization for narrow strings only String concatenations in statements of the form s s abc and s abc are now performed.. s applicable this optimization reduces a sequence of concatenations from quadratic time O n 2 to linear time O n in the length n.. the final result. First of all the optimization replaces concatenations with updates e.g. as if x x a x x b x x c or for that matter..
