When Is It Safe to Move an Object Instead of Copying It?
How the compiler can figure out during compilation when to move objects instead of copying them. - C/C++
Moving Is Not Copying
Like many subtle ideas, the idea of moving data in C++ is built on a simple concept. - C/C++
Copying Container Elements From The C++ Library: It's Trickier Than It Looks
We must generally assume that adding elements to a vector will invalidate every reference, pointer, or iterator that refers to a vector element. - C/C++
The Hazards of Remembering Positions in Vectors
Don't remember pointers, references, or iterators to vector elements until you're done putting new elements in the vector. - C/C++
Aliasing Is Particularly Troublesome With Vector Elements
I would like to continue our discussion with a particularly nasty case in which the result is not well defined. - C/C++
Some Subtleties of Aliasing
Aliasing can cause paradoxical behavior. - C/C++
Sometimes, Making a Program Clearer Makes It Faster
We can "optimize" our code by removing requests for operations that our data structures do not really need to support. - C/C++
Some Optimizations Are No-Brainers
Kernighan's rule for optimizations (Don't do it) is good advice. But as with most rules, there are exceptions. - C/C++
Sometimes Optimizations Cancel Each Other
Two rights can make a wrong in the software-design world. - C/C++
Optimizing a Program Means Making It Run Faster, Right?
People often use optimization to mean changing a program in ways that they think will make it run faster, but that casual definition is far from complete. - C/C++
