Reading and writing binary file
...
If you want to do this the C++ way, do it like this:
#include <fstream>
#include <iterator>
#include <algorithm>
int main()
{
std::ifstream input( "C:\\Final.gif", std::ios::binary );
std::ofstream output( "C:\\myfile.gif", ...
What is the strict aliasing rule?
...ably has instructions to load buff's contents. Then again, maybe you're in C++ and this is some templated header only implementation that the compiler thinks it can inline. Or maybe it's just something you wrote in your .c file for your own convenience. Anyway undefined behavior might still ensue. E...
Why is f(i = -1, i = -1) undefined behavior?
...ans a type like a int, float, or a pointer (see What is a scalar Object in C++?).
Second, it may seem more obvious that
f(++i, ++i);
would have undefined behavior. But
f(i = -1, i = -1);
is less obvious.
A slightly different example:
int i;
f(i = 1, i = -1);
std::cout << i <<...
When to use std::begin and std::end instead of container specific versions [duplicate]
...ld probably use c.begin() due to inertia. I would expect new text books on C++ to recommend the free function version (as it is never worse and sometimes better), but that has to catch up with common usage.
