c++ seg fault:

std::getline(std::istream&, std::string&) is defined in <string>, there's no need to allocate and manage your own buffer in this case. I'll second the post above in doubting that this is really seg-faulting in getline due to allocation issues, Have you tried stepping through the code with a...

Quick question: C++ compare to null?

It is near impossible to write exception safe code in c++ without RAII, smart pointers of some type are required to keep from leaking in the face of exceptions without resorting to try/catch at every level. C++0x/tr1 includes support for additional smart pointers based largely on those found in...

Quick question: C++ compare to null?

In c++, Null is defined to be 0, there is no difference. See Stroustrup

Automated testing in C/C++

I've used Boost Test in the past, it's pretty easy to get started with and does its best to stay out of your way. If you're not already using/familiar with boost, there will be a slight learning curve.

C#, password checking -- would like to use regular expressions library

Without getting into a debate over the better method... (I don't think performance is a valid argument here in either case) This manual method code is creating multiple string copies each time through the inner loop, try this instead: for (int k = 0; k < s.Length; k++) { digitOK =...

What's the proper way to clean up this type of memory allocation (C++)

std::auto_ptr<TYPEDEFD_TYPE> pointerToTYPE((TYPEDEFD_TYPE*)::operator new(Multiple * sizeof(TYPEDEFD_TYPE))); use boost::scoped_ptr or boost::shared_ptr if available depending on needs.

arrays of function calls and memory errors

He's not dereferencing the array, ->* is the pointer to member operator. That said, you should only be calling through to valid function pointers, anything else is undefined and will probably lead to strange runtime behavior.

Stupid C++ question...(should be easy to solve!)

like this? typedef std::vector<int> IntVec; typedef std::map<MyKey, IntVec> MyMap; MyMap map; IntVec vec1 = ...//create/fill vector map.insert(std::make_pair(someKey, vec1)); ... MyMap::iterator it = map.find(someKey); IntVec& vec2 = it->second; vec2.push_back(newInt);

did visual basic 6 have native code or interpreted compiler

Who told you that? Native code will be produced by the JIT compiler at run time - this has the advantage that specific optimizations may be done depending on the currently running target as well as hot spots observed in the running code. Also, you can produce completely native code in visual c++...

C++: Do you flowchart?

I'm of the opinion that it's useless to create any type of documentation unless it's embedded in the source itself. (And even that's of limited value) It may seem like a fine idea when you're first starting a new project, but it'll be worthless when needed the most a couple years down the line...

Overloading an STL function

Especially considering that it's illegal to add anything to the std namespace. Either use a boost ptr_container, or roll your own by layering on top of a standard container.

How to access member of template in C++

You can't. The value is statically bound at the point of instantiation. If you want a different value used, then instantiate the template with this value.

C/C++ prefix vs postfix increment

Don't be so quick to brush him off, if the difference were < 100ms, I would agree with you; we're talking over a second here though. (assuming he didn't decide to do anything crazy at the same time as running the test the second time, this gives at least a rough picture of things) Do you have...
