Save to a Variable instead of print to screen...

I have this code that is printing to the DOS screen, I don't want that. I know in VBA it would be:

Dim IP as Int
IP = ("\n   Source      IP: %s", ipSrc);

How would this work in C
printf("\n Source IP: %s", ipSrc);

There is no such thing as "DOS screen" in Windows!

There are applications working with console — pure console applications of combining console with a Windowed UI; for example, "CMD.EXE" is just one of them.

Yeah, op must have got confused with the UI look of the console application.

Thank you, Tarakeshwar.

It could be. What I cannot understand: as OP is probably a beginner, she or he may never saw a single DOS system... Why so many people still call this thing a "DOS box", "DOS screen", etc. It's actually a normal protected-mode Win32 or 64-bit application.

MERCY! Can't we just call it a DOS BOX for the sake of simplicity instead of a "Normal Protected-Mode Win32 / Win64 Bit Application" ?????

Sergey Alexandrovich Kryukov 26-Apr-11 19:35pm

No. Call it "Console" -- not much longer than "DOS BOX".
(Well, you can call it whatever you want, but do you need correct understanding and appreciation for accuracy?)

I am not sure either. :D

Member 7766180 26-Apr-11 15:20pm

OK, It seems that "Command Prompt" is acceptable. :)

Sergey Alexandrovich Kryukov 26-Apr-11 19:38pm

"Command prompt" and "Console" are different things.
"Command prompt" is a console application. What is generally in a console can be anything, so "Console" is not a "Command prompt".
Seems to be simple enough, isn't it?

Well ... I think for the same reason people who never saw a floppy disk actually saves files by pressing a button with a floppy disk icon over it!
:-O

Wow! Great point. I also was amazed by that fact.
Thank you.

Solution 1

You can use scanf to store the value in a variable. Take a look here.[^]

Isn't there a simpler way? More like VBA?

Solution 3

You can use sprintf() function.
char szIP[256];
sprintf(szIP, "\n Source IP: %s", ipSrc);

I'm not so sure if the code snippet above is right for your question.

Voted 5, proposed as answer.

Member 7766180 26-Apr-11 13:14pm

When <printf("\n Source IP: %s", ipSrc);\> runs I get... 192.168.1.102
Which is what I want. I want to store this so that I may reference it. I simply want to store this IP address. Can I do this?
INT MyIP
MyIP("\n Source IP: %s", ipSrc);

Nish Nishant 26-Apr-11 13:19pm

Yes, that's what xnli has told you. Use sprintf. He's even given example code. try it out, and then please mark xnli's response as the accepted answer. Thanks.

Member 7766180 26-Apr-11 13:40pm

Ok I'm getting closer. Is there a way for a message box to come up so that I can check to see if I am getting the right response?

Nish Nishant 26-Apr-11 13:41pm

Yeah, there is the MessageBox API. BTW don't use this thread for new questions. Start new threads for new questions.

Member 7766180 26-Apr-11 13:43pm

OK, New thread will start.
