可以通过关键字class或struct定义类(区别在于默认的访问权限,目的是保持c++兼容c,所以class默认private,struct默认public),语法如下 class class_name { access_specifier_1: member1; access_specifier_2: member2; ... } object_names; class_name是一个有效的标识符即可,object_names可选,声明体包含的称为成员...

Default is cla0. Section 2.3.4 --float_support={fpu32|softlib|fpu64} Specifies use of TMS320C28x 32- or 64-bit hardware floating-point support. The default is softlib. Section 2.3.4 --tmu_support[=tmu0] Enables support for the Trigonometric Math Unit (TMU). Using this option also...
const and volatile are part of an identifier's type, not its storage class. However, they are often removed from the topmost part of the type when an object's value is fetched in the evaluation of an expression--exactly at the point when an lvalue becomes an rvalue. These terms arise ...
