C++: What is the size of an object of an empty class?
...aligned on a word boundary (such as an integer). For example, if you place char x; int y; inside the class, my GCC clocks it at eight bytes (since the second int must be aligned in that implementation).

Why don't Java's +=, -=, *=, /= compound assignment operators require casting?
...57
or
byte b = 100;
b /= 2.5;
System.out.println(b); // prints 40
or
char ch = '0';
ch *= 1.1;
System.out.println(ch); // prints '4'
or
char ch = 'A';
ch *= 1.5;
System.out.println(ch); // prints 'a'

...hould probably be (m|K) or [mK], because you're not trying to match a pipe character. But that's not important right now.)
If you switch that final match in your command to [mGK] or (m|G|K), you should be able to catch that extra control sequence.

Example

Scanner vs. BufferedReader
As far I know, the two most common methods of reading character-based data from a file in Java is using Scanner or BufferedReader . I also know that the BufferedReader reads files efficiently by using a buffer to avoid physical disk operations.

Why does C++11 not support designated initializer lists as C99? [closed]
...urmountable problems with this approach; given:
struct X {

What order would these functions be called in in c99: struct X foo = {.a = (char)f(), .b = g(), .c = h()}? Surprisingly, in c99:
The order of evaluation of the subexpressions in any initializer i...
