ok so i wanted to learn C++ and got some cool vids(3d buzz tuts), im sure most of u seen em.
So my question is whats the diff in Microsoft Studio 2003 and 2008.
heres a ss:
The 1st one is 2003 one and on the vid it works.
on 2008 however it wont and its the same exact thing. Its like 2008 does not recognize the main function?
*i dont much about c++ so dont flame.

"int main()"
EDIT: just watched some of their tut. Jesus fuck fucking Christ. Get a new tut. 25 minute video on Hello World? Such watered-down material is not conducive to learning. I suggest you check out the sticky and find another tut. http://www.cplusplus.com/doc/tutorial/ is generally recommended.

| Code: | #include <iostream>
using namespace std; // *see comment at end
int main()
{
cout << "Hello World" << endl;
return 0;
} |
the "using namespace std; makes it so you dont have to out std:: in front of things like cout, cin, endl, etc. Also, have to declare the function type. Which is why you make it int main, because you chose "integer main" you are trying to get a value from your function, which is why you return 0.
Feel free to ask anymore questions, also, check out the site HalfPrime posted, it will teach you the basic syntax of c++ much better.

1. you used ( ) instead of { } in your main function.
2. you can essentially wait for input by doing:
std::cin.sync();
std::cin.ignore();
or you can run your program from the command line.
3. never use void main.
