What's the difference between “mod” and “remainder”?
... commonly known as remainder. % is formally the remainder operator in C / C++. Example:
7 % 3 = 1 // dividend % divisor = remainder
What's left for discussion is how to treat negative inputs to this % operation. Modern C and C++ produce a signed remainder value for this operation where the sig...

Resolve build errors due to circular dependency amongst classes
...f in a situation where I am facing multiple compilation/linker errors in a C++ project due to some bad design decisions (made by someone else :) ) which lead to circular dependencies between C++ classes in different header files (can happen also in the same file) . But fortunately(?) this doesn't h...
When & why to use delegates? [duplicate]
...verview
Delegates have the following properties:
Delegates are similar to C++ function pointers, but are type safe.
Delegates allow methods to be passed as parameters.
Delegates can be used to define callback methods.
Delegates can be chained together; for example, multiple methods can be called o...
Why should we typedef a struct so often in C?
...ric, but
they're pretty harmless. However, when
extended to classes in C++, those same
rules open little cracks for bugs to
crawl through.
In C, the name s appearing in
struct s

is a tag. A tag name is not a type
name. Given the definition above,

shared_ptr to an array : should it be used?
...
With C++17, shared_ptr can be used to manage a dynamically allocated array. The shared_ptr template argument in this case must be T[N] or T[]. So you may write
shared_ptr<int[]> sp(new int[10]);
From n4659, [util.smartptr...
What is the meaning of single and double underscore before an object name?
...re convention is widely used not just for private names, but also for what C++ would call protected ones -- for example, names of methods that are fully intended to be overridden by subclasses (even ones that have to be overridden since in the base class they raise NotImplementedError!-) are often s...
Parsing command-line arguments in C?
...to build it (gcc-7.3) and found that the library builds and works, but the C++ test could do with some minor work. iostream.h should become iostream, and using namespace std; should be added. I will mention it to James. This only affects the C++ API test, not the code itself.

Create a pointer to two-dimensional array
...Note that this only works in C, because T[] and T[N] are compatible types. C++ does not have a concept of compatible types, and so it will reject that code, because T[] and T[10] are different types.
The following alternative doesn't work at all, because the element type of the array, when you v...
