what does the command int do?
and can someone explane some simple commands in c++
(i kinda know what cout && cin do but could someone explane it a little)

and how do u make a windows aplication(spelling?)
anyways im using bloodshed (anyone else use this one?)

int variablename;

declares a variable named variablename that can hold an integer value. On most systems an int takes 4 bytes, so 4 bytes of memory are allocated to hold it.

cout sends data to the output stream, so it prints text in a console app.
cin asks the user for input and assigns it to a variable.

As far as windows apps, you'll need to learn windows API and a number of other things, so you'll probably have to be patient.

"int" means something returns an interger or any whole number and i know its used for variables and for int main() so main() must always return an interger but i could be wrong im not through the first chapter in my c++ book yet. i dont know much about making windows aplications exept you need to know about the windows api and you need to go like #include <windows.h> or somethin like that. which is why im sticking with console apps for now.

yeah a type name in front of a function is its return type.

Standard C++ Types
int - integer
float - real number
double - large real number
long - large integer
short - small integer(takes less memory)
unsigned (anyother) - only positive numbers
char - letter
bool - booleen value (either true or false)

<-EDIT->

Oops, I forgot bool, but some compilers don't handle it very well.

Int is one of the smaller forms of variables. there's also char, for letters, short, which is smaller than int, float, i think, carries 4 decimals, and double, i think, carries 8 decimal places. correct me on the long, i think i'm wrong. I too am a n00b at C++ :blink:
Well, this is my first post! i guess i can get help on a board now.

double default carries to the 8th decimal place. you can use setpresision(number of decimal places to go to) i think float is basicly the same im not sure

CODE

double var1,var2,var3;         //pretty sure this is right int main() { var1=1 var2=2 var3==var1/var2 setprecision(9) //pretty sure this isnt right but you something                                                //simmilar if you  want to go to 9 decimal places cout<<var3<<setprecision(9)   //could be this too..... i dunno its late lol return 0; }

well i think ill give my brain a rest now.


**edit** sorry the code looks bad... but it looked good in the window i was typing in oh well im too lazy to fix it :lol:

I think I may go type up another list on these. Maybe later.
