A designator causes the following initializer to initialize of the array element described by the designator. Initialization then continues forward in order, beginning with the next element after the one described by the designator. int n5 = {4=5,0=1,2,3,4} // holds 1,2,3,4,5 int aMAX...
CArray[]有两种实现,区别在于返回值不同。我们来看看代码: template<class TYPE, class ARG_TYPE> AFX_INLINE TYPE CArray<TYPE, ARG_TYPE>::operator[](int nIndex) const { return GetAt(nIndex); } template<class TYPE, class ARG_TYPE> AFX_INLINE TYPE& CArray<TYPE, ARG_TYPE>::operator[](int...

变量初始化(initialization),就是在定义变量的同时给变量设置一个初始值,我们称为 "赋初值"。 数据类型 变量名 = 初始值; 1. 建议在定义变量时给变量设置初始值,虽然不赋值也是允许的,但是我们不建议这么做! int a = 0; // 设置初始值 int b; // 不推荐 ...

Simulink can pass N-D array data to custom code functions in C Caller blocks, and receive data from such blocks. When you do so, you must specify the correct array layout to achieve the intended results. See Default function array layout and Exception by function. For examples of the use...
