C++ Console Lesson 15: Namespace Essentials

[Yikak4]

I'm lazy so I use 'using namespace std;' all the time :P

[aiwasen]

you know what?your music is kinda weird.It reminds me of jesus. But at least I appreciate the tutorial.thanks man

[xThaWolfx]

@aiwasen How can a song remind you of a fairytale?

[bigfanowarriors]

This consludes your life...

[tommyhunter23]

please try to avoid the back ground music... couldn't hear the voice properly.. other wise its really good tutorial... following it... thanks..

[zwerty007]

Its like applying a variable to a variable lol

[Techn0Junki3]

Soo... whats the difference between namespaces and classes?

[BLESSMAN11]

@Techn0Junki3

namespaces lack elements such as;

private (makes data inaccessible to other classes); long story short, one class should mess up the data members of classes with private data

protect(segregates other classes except for friend classes..); its more like that b*tch at school who decides who goes to the party

inheritance (sharing class attributes (like data & functions))...

class are simple superior(and they are the same as structs,) except that structs are public by default

[Techn0Junki3]

@BLESSMAN11 thanks for clearing that up :)

[DigiTan000]

Question! Question! I noticed the function f() and g() didn't receive function prototypes. Is this because their scope was only local?

[1rescen1]

@DigiTan000 Ya, local can't wander to global, cmiiw

[xZippy38]

I'd still rather have have "using namespace std;" in the global scope.

[pumpfever]

This is great, I didn't know about namespaces, it's just used in C++, or also in C?

[jsfowler06]

Hi guys Im learning loads from these videos great work, But is there a way too stop Visual c++ 2010 from qutting console before i have seen the running program? Each lesson im having too add std::cin.get(); too stop it quitting which is ok but anoying..

[FreedomFireGames]

@jsfowler06

c++ 2010 doesent have "start without debug" if you payste the code " system("pause") " at the end of your code then it will fix your problem.

[AaronVlogs]

@FreedomFireGames I know this comment is 8 months old but for people to see in future comments. Yes you can add start without debugging to c++ 2010 just search "How to add start without debugging in Microsoft Visual C++ 2010 express" it's actually very simple

[howitzer24]

@jsfowler06 Put a break point on the line of the closing bracket :)

[CodingMadeEasy]

@jsfowler06 use ctrl f5

[NightOwl79a]

verry nice, i allways put namespace std in the global scope, now i know this is incorect.

[Coi1221]

all ur vids are nice work, what program did u use for that?

[gamemak0r]

this was slightly confusing...

[tivrfoa]

Great video! Thank you!

[sheheryar25]

i m okey with "using namespace std; "

[VicariousVirzo]

@sheheryar25

no shit :D

[FallofDarkness55]

@sheheryar25 without using the namespace std from the standard c++ library, you will get errors when using the commands that perform input-output operations. cout and cin belong to the standard namespace defined in the c++ standard library therefore you have to define this globally "using namespace std;"

[iceshadow625]

@FallofDarkness55

you don't have to define it globally. he hasn't been defining it globally so far. Sure defining it globally makes it easier, but I prefer to define them in the scope I use them generally. that way I can keep things organized and clean, with only a few ways out, you can control the flow of your program better.

[chulove522]

@sheheryar25 so do i~

[rhillner]

great, thanks

[JJovola]

dude why dont u just do using namespace std; in the beginning?

[MrTakeAshot1]

JJovola, the answer to your question is at 2:36-2:40
