I just got DEv- C++ compiler from a cd contained in a book I just bought. I can't get it to compile anything!! I write the program:
#include <iostream.h>
int main()
{
cout<<"Hello world";
}
return 0;
Then I compile(which by the way, do I have to save in a certain location?) and i click on the icon which is just for the source code, not the exe file. Then if i click run, it says the source is not compiled. Anyone have suggestions?

Add a "cin >> " statement, the window closes at the end of every program, you need something to keep it open and the "cin >>" statement should do it.
The "return" statement should also be in the "int main()", additionally, are you hitting run after it says that the source has been compiled?
If you do not specify a location to which the compiled code must be saved it get saved into the default location.
With borland it is somewhere deep inside the 'program files' but I don't know for your compiler.
You must have givin it a name so do a search for the program.
Like 'dir /s hello.exe'. (use the name you gave the proggie).
noODle, no I have Dev and you don't need to specify anything, everything is done for you... it has a GUI... you ought to try it.
The same thing happened to me... i think the one in the book is defective... i just downloaded another one from www.bloodshed.net/ but if you really want to keep that one all you have to do is modify the sample apps that come with the cd.
when you return a value, you must be inside a function?
when you type "return 0;" that is the value you are returning for "int main()"
Code:#include <iostream.h>
int main()
{
cout<<"Hello world";
return 0;
}
yeah tampabay was right, you must have a main() function and your return 0; has to be inside of main() Also, you shouldnt use #include <iostream.h> That is bad programming style because it is so old. If your using a very old compiler that is ok, but hopefully you are not. Instead use:
#include <iostream>
using namespace std;
This is better style.
Also i would suggest that you read the little book that teachs you how to use your compiler...i think it will answer a lot of your questions :)
