Can the \'streaming\' algorithm like std::transform or std::partial_sum read from and write to the same place?
Does the following code invoke undefined behavior (due to aliasing violation or otherwise)? int foo(int (*a)[10], int (*b)[5])
At the moment I am experiencing a really weird behavior of my Mac App. On my Mac (and on all other testing Macs) everything works fine. The app simply works, no leaks,...

I have a relatively large class that I\'m working with and it\'s all worked fine so far (note: I didn\'t actually write the class, I\'m just adding some functionality).However, after declaring one mor
int&fun() { int * temp = NULL; return *temp; } In the above method, I am trying to do the dereferencing of a NULL pointer. When I call this function it does not give exception. I found when retu
I accidentally came across $(undefined) in a statement below, where params is an object: var $this = $(params._this) || $(this);
I came across this code: #include<stdio.h> void main() { int x; float t; scanf(\"%f\",&t); printf(\"%d\\n\",t);
