Hello Friends,
I the following code given below
#include <iostream.h>
void fun()
{
cout <<"in function one " << endl;
}
int main()
{
fun();
return 0;
}
The above program is complied and the output is shown
"in function one".One thing please notice that the function prototyping is not done here.
In the second the cpp program
#include <iostream.h>
int main()
{
fun();
return 0;
}
void fun()
{
cout <<"in function one " << endl;
}
In the second cpp program the function "fun()" is defined after the main().
This cpp shows an error which is given below.
//////////////////////////////////////////////////////////////////////////////
mpiling...
fun2.cpp
d:\c++\fun2\fun2.cpp(6) : error C2065: 'fun' : undeclared identifier
d:\c++\fun2\fun2.cpp(11) : error C2373: 'fun' : redefinition; different type modifiers
Error executing cl.exe.
fun2.exe - 2 error(s), 0 warning(s)
//////////////////////////////////////////////////////////////////////////////
In the first the cpp program the , the function declaration and the body is done before the main .In the cpp program the function declaration ie function prototying is not done here.
In the scecond cpp program, the funtion is defined, after the main function. the cpp program shows the error which is given above.If the function prototying the funtion is given ie. declaration function before the main , the above error can be avioded.
Can any one tell me what is the difference between the two programs.
Hoping for a reply.
Yours,
Phijo

You've pretty clearly said what the difference is. C++ requires the prototype of the function before it is used. In the first case, you've defined the function itself before its use, so it compiled fine. In the next case, the compiler was not able to see the prototype for fun() when it was used in main(), so it complained.
In C, you can get away without declaring a function if the function takes no parameter and returns an int. The C compiler assumes that prototype if it doesn't see one. That is not legal in C++ though.
Regards
Senthil

your first sample program.....
#include
void fun()
{
cout <<"in function one " << endl;
}
int main()
{
fun();
return 0;
}
workz fine coz the compiler lookz for all the function that are defined above it!!!!!
your second program......
#include
int main()
{
fun();
return 0;
}
void fun()
{
cout <<"in function one " << endl;
}
doesnt work coz as said the compiler lookz for all the function definitionz that are defined above the main function.....
if u have to get thiz above code working.....u have to give the compiler the indication that there is a function defined by giving a formal definition function prototype.....
coz once it reaches the void main it executes the code and findz ur function that is defined(with no prototype) as an undeclared type!!!!!.....
cheerz.....

I have this app that opens a bitmap image and displays it in the dialog. However, when I move it off screen then back on, the portion that was offscreen but is now on screen is not refreshed. I think I have to handle some kind of message like WM_PAINT somewhere but I don't know quite where to do this exactly. I'm thinking of overriding CCmdTarget::OnCmdMsg and doing it in there somehow. Rather than making an uninformed guess at the best way at doing this and wasting time writing code I don't need, I'd like to ask up front as to what's the best way to do this. I'd like to redraw when the window is placed in it's final location (after left mouse button is released) but I would like to redraw it more intelligently after I get this part figured out. Any help would be greatly appreciated and thanks to all the people that have helped me in the past with this app.

You should do all your drawing in your WM_PAINT handler. Your window will recieve WM_PAINT messages from the system whenever it needs redrawing, for whatever reason.

hey use the WM_PAINT directly!!!!!.....dont waste ur time writing a fuction such as OnPaint() by urself when there is an already well handled one.....it will do all the repaintz that are required automatically!!!!!
hope thiz helpz.....
just select ur class wizard and set the class name as the class name of the dialog,then in the messages box,look for WM_PAINT,double click it and it adds to the member function box as "OnPaint()".....click on the OK button.....
then in ur dialog cpp go to the added function(OnPaint()).....
then write the code that is needed to diplay the bitmap on the screen using BitBlt().....
if u have to load an image in to ur screen u must be using the dc memory.....
herez a n example code.....
void CXYZDlg::OnPaint()
{
dc.BitBlt(offsetx,offsety,m_size.cx,m_size.cy,m_dcMem, 2, 0,SRCCOPY);
}
look into BitBlt for more info.....
maybe thiz article could aso help u out!!!!!......

the time taken to writing ur own paint finction is a waste of time and unnessar effort when the OnPaint() od the MFC handles thiz cery neatly!!!!!

You no need to handle any other messages for this. Just write your code that displays the image inside the OnPaint or WM_PAINT.

Personally I think they are like having a shower in a raincoat.
Or do you mean you want to know how to write destructive software ? In that case, grow up and go home.

Trojans:
1) Universify of Southern California (USC) students (or at least the school mascot)
2) The people of Troy that were tricked into dragging in that very big wooden horse into their walled city.

Oh, I thought they were condoms.... *grin*
He's written to tell me that he wants to capture the screen, including the contents of video files that are playing. Still trying to work out what that has to do with trojans.

I've been using VS6 with the MSDN installed for some time and until recently hadn't used the FAVORITES tab in the MSDN help. What I began to notice was that the FAVORITES list entries keep disappearing. Once I had gotten into it I had quite a few entries and after several days I closed VS (which closed the help of course). Next day, poof!
Is there a way to get the MSDN library help to retain it's favorites entries?
thanks gang

Normally it does keep them. I've had them disappear a time or two over the years but simply wrote it off as the moon being out of phase. It may be overkill but after adding one, exit MSDN right away.
