How do you copy the contents of an array to a std::vector in C++ without looping?
...C-style arrays are perfectly valid containers for most STL algorithms--the raw pointer is equivalent to begin(), and (ptr + n) is equivalent to end().

uint8_t vs unsigned char
...8 bits. Both places are where space matters and we often need to look at a raw dump of the data when debugging and need to be able to quickly determine what it represents.
The first is in RF protocols, especially in narrow-band systems. In this environment we may need to pack as much information as...
Which C++ idioms are deprecated in C++11?
...lly deduced would help a lot making the syntax more easily comparable to a raw loop.
Basically, reading algorithms made with standard algorithms are far easier as words hiding the implementation details of the loops.
I'm guessing only higher level algorithms have to be thought about now that we ha...
count vs length vs size in a collection
... size and that's also what I wrote in my reply. Whenever we are talking of raw bytes we are talking of size IMHO and a file with no closer specific content is just a bunch of bytes. Length is usually not used for expressing byte count but to express a accumulation of elements stringed together (byte...
Multiple arguments vs. options object
...the last three are optional.
So why not do this? (Note: This is fairly raw Javascript. Normally I'd use a default hash and update it with the options passed in by using Object.extend or JQuery.extend or similar..)
function map(nodeList, callback, options) {
options = options || {};
var t...
What is the difference between string primitives and String objects in JavaScript?
...itive data type. It has no methods, it is nothing more than a pointer to a raw data memory reference, which explains the much faster random access speed.
So what happens when you do s.charAt(i) for instance?
Since s is not an instance of String, JavaScript will auto-box s, which has typeof string ...
Fast way to get image dimensions (not filesize)
...know how much room it must reserve before starting to read the file. Some "raw" type file formats might just be a stream of bytes with some "end of line" byte at the end of each horizontal row of pixels (in which case the software must read the first line and divide the size of the byte stream by th...
What is the difference between buffer and cache memory in Linux?
...er caches. Since 2.4, the page and buffer cache are unified and Buffers is raw disk blocks not represented in the page cache—i.e., not file data. The Buffers metric is thus of minimal importance. On most systems, Buffers is often only tens of megabytes.

Why is it OK to return a 'vector' from a function?
...ain successes of modern C++ style. But you seem to be stuck thinking about raw arrays and pointers, so I wouldn't expect you to grasp that.
