C++: Why do people avoid certain statements / structures?

We have noticed out of reading a lttle bit around right here, as well as cpluscplus.com in which there is a bit of…prejudice in opposition to certain kinds of coding.I got wondering in the event that people might clear the following up for me:

implementing statements:Have you thought to I you should not particularly like typing a sexually transmitted disease::before every cin / cout
Arrays.A lot of people seem being anti-array, along with insist in using vectors.Concerning yet to recognise why, as well as guides We’ve seen online about vector usually are not a very big aid on doing me understand this matter.
Pointers — I have noticed ideas getting many love via people, in particular here in yahoo the answers, I never really have why nevertheless.From just what I’ve realized in this studies, isn’t a pointer merely a simple strategy to point to somewhat of a variable or a place in a spectrum / subject Couldn’t this specific be done just like easily by using variable notation

int players
ptr * my partner and i = players

cout << players0 << endl;
cout << *i << endl;
S
Shouldn’t your above be the identical (also, I put aside if I’m speculated to have that * when I’m utilizing it as any cout, as that might just output the positioning in memory)

Any help clearing these items up will be delightful.

C++ is often a complex language with many several, often contradicting, capabilities.It is incredibly easy to provide risky, cart, or unmaintainable solutions by picking the wrong tools to the tasks.It’s been known for some time, and it is pretty popular now, just what works and also what does not.

Think about getting Sutter/Alexandrescu’s “C++ Coding Standards”
http://www.gotw.ca/publications/c++cs.htm which belongs to the most latest best practitioners books, which explains that tools are wrong and also why, influenced by the built up experience from the C++ programmers.
Other best practices books will be the Effective C++ and also Exceptional C++ set, which get a lot more in-depth upon each option.

With regards to your points
ONE PARTICULAR.”using namespace” directives is a major dilemma in header files (chapter 59 involving Coding Standards):imagine including a header that has using namespace std;, another header which includes , and then attempting to utilize a variable called “int count; ” or maybe “max” and also “list” or “swap”.You will discover just too many names this suddenly clash with archives functions plus types if your entire namespace an std is pulled together with a making use of directive, in addition to, if this proceeds from a header document, the crashes can seem in *your* source code simply because some unrelated header archive was changed by just a programmer throughout another unit.

Within source information, they are no issue, but they ensure it is harder pertaining to others to read a person’s code (I find “count” and possess to speculate, did a person mean an std::count and also some matter you characterized earlier.If you are using boost, then there are also collisions somewhere between names characterized in a sexually transmitted disease::and inside boost::)

One instance when “using” is usually used is “using an std::swap; “, so that it possible to the compiler that will automatically work with optimized swaps in the event that provided and the generic swap or.

2) Vectors will be the default storage units in C++ (chapter 76 associated with Coding Standards)
