Thread: starting programming c+ with visual studio 6.0

well i was reading here
http://www.chapman-lab.uaf.edu/visualGuide.html
how to begin. i created a workspace called CS201
project called hw1, and a source file called problem1_1.
now do i have to use this names(cs2001 for workspace, hw1,hw2,hw3 for project and problem1_1 problem1_2... for source files)?.

k but that isnt that importent, but i got some problems when i started to use.
- first of all, after i close the visual studio, enter again and open the workspeace, when i try to run the programm (creat hw1.exe) so it says:

--------------------Configuration: hw1 - Win32 Debug--------------------
Linking...
LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/hw1.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

hw1.exe - 2 error(s), 0 warning(s)

what is that means?

- why when i write a code it dissapear after a sec? how to keep it?.

- when i type

#include <iostream.h>

int main (void)
{
cout << "Hello World";
}

it doesnt show me the "hello world". why?


i'll glad to get help. thx

ok. now i noticed sometimesi got the trouble that i cant save the hw1.exe even without closing and oppening the program again, and the code of hello world works but why is it only when i press on "excute program" and not in "go" ?

actually i understood almost everything. just i dont know how to make my page not dissapear after a sec

I assume you are asking for keeping the console screen.
IN case of VC++ when you run the code in debug mode unless you require any input from user the program will close itself (or terminate) after it's work is done. So if you want to see the output you can set up break points (read help in VC++) and go to each statement step by step.

2) Another way to keep the scree is to run the exe file directly. You can see an exclamation mark symbol on the top icons click on that and you will be able to see the screen.In the end it will mention "Press any key to continue"

3) One other way is just to give one more statment in the end
cin<<user_input;
unless you press any key the screen won't go

Hope this helps
