The empty default constructor like Widget() {}; is seen as a user defined default constructor, while Widget() = default; is not. This leads to default initialization in the former case, while value initialization in the latter, in definitions involving the form Widget w = new Widget(), Widget w{} etc.

FOO="${VARIABLE:-default}" # FOO will be assigned 'default' value if VARIABLE not set or null. # The value of VARIABLE remains untouched. To do the same, as well as assign default to VARIABLE:
Is it possible to set default values for some struct member? I tried the following but, it'd cause syntax error: typedef struct { int flag = 3; } MyStruct; Errors: $ gcc -o testIt test.c test....
Default value of MyObject. See default Keyword in Generic Code (C# Programming Guide) (MSDN): In generic classes and methods, one issue that arises is how to assign a default value to a parameterized type T when you do not know the following in advance: Whether T will be a reference type or a value type. If T is a value type, whether it will be a numeric value or a struct. Given a variable t ...
