Difference between size_t and std::size_t
...
C's size_t and C++'s std::size_t are both same.
In C, it's defined in <stddef.h> and in C++, its defined in <cstddef> whose contents are the same as C header (see the quotation below). Its defined as unsigned integer type of t...
Why does the use of 'new' cause memory leaks?
I learned C# first, and now I'm starting with C++. As I understand, operator new in C++ is not similar to the one in C#.

strcpy(cstr, str.c_str());
// do stuff
delete [] cstr;
Or in modern C++:
std::vector<char> cstr(str.c_str(), str.c_str() + str.size() + 1);

In C# what is the difference between a destructor and a Finalize method in a class?

~ClassName() { }
The above is syntactic sugar for a Finalize function. It ensures that the finalizers in the base ar...
What is external linkage and internal linkage?
...also put classes. The linkage for anonymous namespaces has changed between C++98 and C++11 but the main thing is that they are unreachable from other translation units.
namespace {
int i; // external linkage but unreachable from other translation units.
class invisible_to_others { };
}
