I found a great c++ snippet archive

Where I stopped skimming:

Code:

while (! myread.eof() )

Perhaps because the originator needs to learn a little more first?

[Visit the FAQ to see why. If you go against an FAQ, count yourself in the beginners-intermediate group.]

Beh, the site saw me coming, and refused to let me in to have a look....

Nice broken link...;)

- The user input snippet is awesome!

- I also like the delay snippet. It's important to put your processor at 100% when delaying an action.

- The Combine Two Strings function is essential! It's easier to call a function with the prototype string addstrings(string a,string b) than to write a + b!

I also like using namespace std; all over the place, overflowing ints here and there, the caring concern for proper indentation, the use of C-style casts and this particular snippet of code to convert a string to a float got itself a place in my heart.

Code:

---

template <class T>
bool from_string(T& t,
const std::string& s,
std::ios_base& (*f)(std::ios_base&))
{
std::istringstream iss(s);
return !(iss >> f >> t).fail();
}

---

The masterful indentation, the little detail of breaking the function header in two lines and the absolute geniality behind this useless... useful piece of code.

Vulnerable.

its not good c++??
it worked for me.

do you know of a page that has a bunch of c++ operations like this that are better? Please share Because i haven't been able to find it. Thats really why i posted this thread.

Those two properties traditionally have no relation in C++.

Familiarize yourself with what is offered by this site. It offers an astounding amount of stuff, written by some of the best C++ programmers out there.

yea, i suck at programing in c++, but i can program in it just because of a bunch of code snippets. I figured that would be usefull to someone else. But if its terrible c++, i dont want to loose respect of all the c code masters.
I took the page down.

can you guys tell me they easy way to set up a c++ option parser?

c++ option parser = ?

If you are finding it hard to learn the language, then get a good beginners book. Looking at code written by proffesionals is likely to get you even more lost and confused. These are people with years of experience. Saying that, everybody has to start at the beginning of somthing new. No one person can ever learn the language inside out and back to front. Its just not possible, its too big. ( C is different, in comparason it is quite a small but complex language ) You just need to learn all the basics, learn them well then put all this into practise with coding your own programs. You then have to pick at the language and take out the bits and preices you "need" to learn for whatever reason you want to program. ( Ie: games ).

You mean like this - http://clusty.com/search?query=getop...Mozilla-search
There are many ways (and libraries) to do this for you.
Or you can be inspired and make your own.

Well, since I already recommended Boost in this thread, saying that it has an amazing amount of things ...

Thanks Mario F.
Tclap works great!
its actually really macintosh compatible.
sweet.
