Why use pointers? [closed]
...and much confusion. ;-) If we talk about simple data types such as int and char there is little difference between an array and a pointer.
These declarations are very similar (but not the same - e.g., sizeof will return different values):
char* a = "Hello";
char a[] = "Hello";
You can reach any e...
LPCSTR, LPCTSTR and LPTSTR
...o a const string (LP means Long Pointer)
LPCTSTR is a pointer to a const TCHAR string, (TCHAR being either a wide char or char depending on whether UNICODE is defined in your project)
LPTSTR is a pointer to a (non-const) TCHAR string
In practice when talking about these in the past, we've left ou...

Undefined reference to static constexpr char[]
I want to have a static const char array in my class. GCC complained and told me I should use constexpr , although now it's telling me it's an undefined reference. If I make the array a non-member then it compiles. What is going on?

Concept behind these four lines of tricky C code
... {
m[0] *= 2;
main();
}
else
{
printf((char*) m);
}
}
It recursively calls main() 771 times.
In the beginning, m[0] = 7709179928849219.0, which stands for C++Suc;C. In every call, m[0] gets doubled, to "repair" last two letters. In the last call, m[0] cont...
