在本章中,我们将完全用C语言,实现面向对象中最重要的几个概念,分别是继承,覆盖。我们先看实现后的调用: int main (int argc, char ** argv) { void * p; while (* ++ argv) { switch (** argv) { case &#…
In this case, we know that i + b = o + t. Since C defines for loops in terms of while loops [Ker78], we can use this construct to build for loops as well. User constraints can easily be added to an integer linear program. The user could, for example, bound the number of ...
