Instead, it should be rewritten in order to: Use n to validate index. Use an unsigned type for index. Treat an out-of-bounds access to a as an error. For example, by calling an error-handling function if index is invalid. extern int error_handler(const char *message); /* *a : Po...

• In C++, by default, a const value is local to the file in which it is declared. However, it can be made global by explicitly defining it as an extern variable, as given here. extern canst max=10; In C, by default, canst value is recognized globally, that is, it is also vis...

The layout of linkage specification blocks can now be customized via two formatting settings,Indentation | Indent linkage specification block membersandBraces Layout | Linkage specifications. The usual idiom of usingextern "C"blocks in header files to create an API compatible with C is now supported...
