Beginning C++

can i ask you how can i edit a dll file? sorry for my noob question

Basically You can't. You could disassemble using IDA Pro/OllYDbg or the like, but that is quite complicated and not something you'd be doing in a day, depending of course on the complexity of the DLL. Knowledge of assembly is needed. Basically you aren't editing the DLL, but rather remaking it :/

C primer edition 5 is good but for some reason everything I try in there closes its self
before I can complete for example:


// getinfo.cpp -- input and output
#include <iostream>
int main()
{
using namespace std;
int carrots;
cout << “How many carrots do you have?” << endl;
cin >> carrots; // C++ input
cout << “Here are two more. “;
carrots = carrots + 2;
// the next line concatenates output
cout << “Now you have “ << carrots << “ carrots.” << endl;
return 0;
}

Right after I type how may carrots it closes,
I even tried adding cin.get(); still happens though any ideas?

did you put cin. get () just before return 0;?

Yes I did.

I did it like this:

#include <isostream>
int main()
{
usingnamespace std;
int carrots;
cout <<"how many carrots do you have?" <<endl; I like \n better :O
cin >> carrots + 2;
cout << "Now you have " << carrots << " carrots." <<endl;
cin.get();
return 0;
}

using namespace std; should be right after #include iostream and not in int main maybe that is the problem

Hmm even though i changed it it still happends.

post the exact same source code you are compiling

Keep in mind I'm using Visual C++ 2008 Express Edition.

#include "stdafx.h"
#include <iostream>

using namespace std;
int main()
{
int carrots;
cout << "How many carrots do you have?" << endl;
cin >> carrots;
cout << "Here are two more. ";
carrots = carrots + 2;
cout << "Now you have " << carrots << " carrots." << endl;
cin.get();
return 0;
}

occasionally I get these problems too. I think it happens when I run Google Desktop in the background. This is why I just use system("pause"); instead of cin.get();

If one cin.get() doesn't work sometimes you need 2. I believe the book outlined things like this near the beginning. And the namespace doesn't have to be under #include, especially in a single function program Like this.

You Sir saved me system("pause"); worked perfectly!

DON'T USE system("pause);
It's not always the greatest choice, as sometimes it refuses to work.
Instead, use cin.get(); twice like this

cin.get();
cin.get();
