cmd close's too soon...

Hello! I need some help on how to stop the consol from closing. I'll put a <---- Where it cuts off.

Code:

---

#include <iostream>

using namespace std;

int main()
{
int a, b, c;
cout << "Hello!\nPlease Enter Any Whole Number:";
cin >> a;
cout << "Alright!  You entered ";
cout << a;
cout << "\nAlright! Now Enter Another Whole Number:";
cin >> b;
<----- (Cuts off here)
cout << "Alright!  You entered ";
cout << b;
cout << "\nNow where going to add ";
cout << a;
cout << " and ";
cout << b;
cout << "!\n";
c = a + b;
cout << c;
return 0;
}

---

I have no idea on how to make it wait to the end to close. :( Any help please? (I didn't comment the code since it's so basic.)

add a, im still new at this to...i had this problem as well

Code:

---

cin.get();

---

so it waits for enter at the end

Your program works fine.
If you mean with "program cuts off" that the window closes before you can see the output. Call it from the commandline or search the forum.

Common problem - the second half of your program is entirely output. Once all the text has been written to the screen, the computer considers the program finished, so the console window in which it was running is finished. The simple solution is just to request some user input at the end, like rodrigorules suggested. (Running the program in a console like ZuK said would work - but it's a bit of an inconvenient solution most of the time). You can find several other solutions in the FAQ, and there are pros and cons of each - just pick one that works for you.

Well, hasn't cleared the stream, so he would need two cin.get(); or a cin.ignore() and cin.get().

dimirpaw, its in the FAQ.

or you could just add:

Code:

---

while(2 == 3)
{
}

LOL, that made my day. I've seen that one before.I can't tell if you were joking or not.

It doesn't work though because 2 doesn't equal 3. It turns into while(0) which never gets executed.

i was joking...

all depends if you put while after the code it would generate the code at least once. but still yet you still have to have cin.get();

Well his code wasn't a do...while.

That was funny ElastoManiac, don't get many jokes around here. ;) There isn't even a laugh smilie.... ....

Yep I used cin.get(); more then once it wont work because when you input a number it takes it as your pressing enter to quit, and yes I'm reading the FAQ's, however I have other things to do so I cannot read it all now... However I'll try what Dae said, thanks.

EDIT: Thanks Dae's works now!

Code:

---

#include <iostream>

using namespace std;

int main()
{
int a, b, c;
cout << "Hello!\nPlease Enter Any Whole Number:";
cin >> a;
cout << "Alright!  You entered ";
cout << a;
cout << "\nAlright! Now Enter Another Whole Number:";
cin >> b;
cout << "Alright!  You entered ";
cout << b;
cout << "\nNow where going to add ";
cout << a;
cout << " and ";
cout << b;
cout << "!\n";
c = a + b;
cout << c;
cin.get();
cin.get();
return 0;
}

Actually, the entire code is being processed and printed. When the program reaches the end of main() it quits. You just aren't able to see the parts after you enter the second number being printed because it prints them, and reaches the end of main() where it quits. Its hard to see whats printed before it reaches the end and knows it needs to quit. I'm able to see the things printed before the app closes, for a split second. The reason it doesn't quit and asks you for numbers is because cin halts the position in the code and waits for input, so it hasn't reached the end of main(). The same goes for cin.get(), it halts the program and it waits for one character to remove from the stream.

When you enter something in cin you push enter, the part entered is extracted and stored in the variable, but the 'enter' command is still in the stream.

So when you call cin.get() later in the program (and you've called cin), you still have that enter command in the stream, so it simply extracts that and continues with the program, so you have not paused at all - just removed that one command. So you call cin.get() again to wait for another character because theres nothing in the stream (unless you didn't extract all the rest of the characters from the stream, which isn't done often). So it pauses, and waits for the enter command. I think its '\n' in the stream, but I'm not sure.. I haven't read up on much of C++ in a few months. If I'm wrong somewhere you can be sure someone will mention it or elaborate on it.

Or cin.ignore() first will clear the entire stream, and then you can call cin.get() which will wait for a character to extract from the stream since cin.ignore() just cleared it.

That was longer that it should have been >.<, read http://www.cplusplus.com/ref/iostream/istream/get.html for more info - cplusplus.com is a good reference for the details of the library.

Alright, I didn't read all of what you said since I gota go in a few minutes. I got a lot of C++ Books about 20 or so, on Game Programming, Database's, ect... I have this really big one called Visual C++ 101 Tips, not bad. (Most of the stuff in there can be related to any other compiler.)

Well I hope I can learn C++, personally I don't care to Learn C then C++, I'm already in Expert in Visual Basic with well over 6 years of experince. Not bad it wouldn't really matter for learning C++. Only the concepts about int, ect... I can carry on. :(

This is much simplier, you just press enter at the end of program - and thats it.

Code:

---

#include <conio.h>

// at the end
cout<<"Press a key to continue...";
getch();

---

Well I'll stick to cin.get() for now, "getch();" gives me errors so... Well I must go to work so I cannot read up about it now, thanks anyways! :)

Thats the same as:

Code:

---

#include <iostream>
using namespace std;
// at the end
cout<<"Press a key to continue...";
cin.ignore();
cin.get();

---

Accept you wont have to include some wierd conio.h C header file. :p

Cool. However that book is about C++, MFC, and VC++ (which is a compiler you arent using). Not only that but its 1100 pages longer than it needs to be for just learning C++ concepts, and has a rating of 3.5 at amazon. I would recommend (especially if you have it) Accelerated C++ as its more appropriate when you're trying to learn new concepts, and has a rating of 5. (well its 4.5, but thats because 1 out of 100 people voted 4 instead of 5).

Yep I use VC++ 6 but thats rare of me! :O Well I'll tell you my book list when I get back, well bye!

conio.h is not a standard header file from either the C or C++ libraries - not everybody has it.

Alright I looked through some of my books, here is a small list.

Accelerated C++ (I found out I had it! :))
Visual C++ 101 Tips
C Programming How-To
The C Programming Language
Sams: C++ Primer Plus (2005 EDITION)
Sams: Tricks Of The Windows Game Programming Gurus
C++ Programming with the Standard Template Library (SDL Tutorial and Refrence Book)
Beginning C++ Game Programming
Algorithms Data Structures and Problem Solving with C++ (Don't ask me why I even have this)
Data Structures and Algorithms with Object-Oriented Design Patterns in C++ (Another one of those don't ask me why I even have)
Advanced 3D Game Programming using Direct X 9.0
C++ Weekend Crash Course
Programming Role Playing Games with Direct X 8.0
Masturing Visual C++ 6 (May never read)
Visual C++ 6 for Dummies (May never read)
Practical C++ Programming
Game Programming All In One
Sams: Teach Yourself Visual C++ In 24 Hours (May never read)
Strategy Game Programming With Directx 9.0
Sams: Teach Yourself Visual C++ 6 in 21 days (May never read)
Sams: Tricks of the 3D Game Programming Gurus
Sams: Visual C++ 4 Unleashed (Very old, and never will read)
Visual C++ 6 Unleshed - MFC Programming
Visual C++ and MFC Programming
Wrox: Professional C++

Well thats a big list, took some time to type out! :) Are any of these good for learning at all? I haven't looked through most of them just a few game programming ones. I'll read that Accelerated C++ as soon as possible though! :)

Any other books I should have?

Accelerated C++ and Sams: C++ Primer Plus together are a lethal combo to learn C++, and the only other one to learn C++ that you might need is The C++ Programming Language (Special 3rd Edition) by the creator of C++, Bjarne himself, as a reference of the advanced topics.

Tricks of the 3D Game Programming Gurus looks alright, but I personally wouldn't read anything by LaMothe.

Why aren't you sure why you have books on Data Structures and Design Patterns? those are huge topics in game programming. Data Structures and Algorithms with Object-Oriented Design Patterns in C++, looks to be a great book if you're in college studying for in CS, and is on my to-read list. But Algorithms Data Structures and Problem Solving with C++ isn't holding much of a rating.

I don't know what you're shooting for, but the only ones out of that list I would read are the two C++ books, and possibly the 3d game programming one. Then after that I would go for.. two on data structures, one on the STL, and one on DirectX or openGL.

I write down all the good books that I would read if I needed to learn the material. Its pretty much in categories, and in order of which one I'd read first. I'd look up any book you want to read on amazon.com first, at least.
