In unmanaged C/C++ code, what are the best practices to detect memory leaks? And coding guidelines to avoid? (As if it's that simple ;) We have used a bit of a silly way in the past: having a counter increment for every memory allocation call and decreme...

I'm trying to learn C. As a C# developer, my IDE is Visual Studio. I've heard this is a good environment for C/C++ development. However, it seems no matter what little thing I try to do, intuition fails me. Can someone give good resources for how to eithe...

Even though I have a robust and fast computer (Pentium Dual Core 2.0 with 2Gb RAM), I'm always searching for lightweight software to have on it, so it runs fast even when many apps are up and running simultaneously. On the last few weeks I've been migrat...

How do you create a static class in C++? I should be able to do something like: cout << "bit 5 is " << BitParser::getBitAt(buffer, 5) << endl; Assuming I created the BitParser class. What would the BitParser class definition look like...

Why are pointers such a leading factor of confusion for many new, and even old, college level students in C or C++? Are there any tools or thought processes that helped you understand how pointers work at the variable, function, and beyond level? What a...

I'm looking for a tool which can generate makefile for a C/C++ project for different compilers (gcc, microsoft vc++, borland etc) and different platforms (Win, Linux, Mac).

I develop C++ applications in a Linux environment. The tools I use every day include Eclipse with the CDT plugin, gdb and valgrind. What tools do other people use? Is there anything out there for Linux that rivals the slickness of Microsoft Visual Studi...

I was looking at the API documentation for stl vector, and noticed there was no method on the vector class that allowed the removal of an element with a certain value. This seems like a common operation, and it seems odd that there's no built in way to do...

VC++ makes functions which are implemented within the class declaration inline functions. If I declare a class Foo as follows, then are the CONSTRUCTOR and DESTRUCTOR inline functions? class Foo { int* p; public: Foo() { p = new char[0x00100000...

I want to know what a "virtual base class" is and what it means. Let me show an example: class Foo { public: void DoSomething() { /* ... */ } }; class Bar : public virtual Foo { public: void DoSpecific() { /* ... */ } };

I come from a Java background, where packages are used, not namespaces. I'm used to putting classes that work together to form a complete object into packages, and then reusing them later from that package. But now I'm working in C++. How do you use name...

The following C++ code uses a ifstream object to read integers from a text file (which has one number per line) until it hits EOF. Why does it read the integer on the last line twice? How to fix this? Code: #include <iostream> #include <fstream...

I've been writing C and C++ code for almost twenty years, but there's one aspect of these languages that I've never really understood. I've obviously used regular casts i.e. MyClass *m = (MyClass *)ptr; all over the place, but there seem to be two othe...

Maybe this is a dumb question, but is there any way to convert a boolean value to a string such that 1 turns to "true" and 0 turns to "false"? I could just use an if statement, but it would be nice to know if there is a way to do that with the language o...

In the C and C++ programming languages, what is the difference between using angle brackets and using quotes in an include statement, as follows? #include <filename> #include "filename"

I have a .exe and many plug-in .dll modules that the .exe loads. (I have source for both.) A cross-platform (with source) solution would be ideal, but the platform can be narrowed to WinXP and Visual Studio (7.1/2003 in my case). The built-in VS leak det...

Basically I want tools which generate source code visualization like: function call graph dependency graph ...

How do I list the symbols being exported from a .so file? If possible, I'd also like to know their source (e.g. if they are pulled in from a static library). I'm using gcc 4.0.2, if that makes a difference.

Any good suggestions? Input will be the name of a header file and output should be a list (preferably a tree) of all files including it directly or indirectly.

How do you set, clear, and toggle a bit?
