what virtual functions provide is called run-time polymorphism , and what templates offer is called compile-time polymorphism or parametric polymorphism. (查看原文)
In either case, we manipulate objects that share a common set of operations. If no hierarchical relationship is required between these objects, they are best used as template arguments. If the actual types of these objects cannot be known at compile-time, they are best represented as classes derived from a common abstract class. If run-time efficiency is at a premium, that is, if inlining of operations is essential, a template should be used. (查看原文)
extern specifies a linkage convention, instead of a language convention. so extern ＂C＂ is often used to link to fortran and assembler codes which conform to C convention.

The connection between the language in which we think/program and the problems and solutions we can imagine is very close. For this reason, restricting language features with the intent of eliminating programmer errors is at best dangerous...a language provides a programmer with a set of conceptual tools; if these are inadequate for a task, they will simply be ignored.
