to pass an array of pointers to a function, you define the function parameter to match the type and size (optional) of the array. in c/c++, a function to accept an array of pointers to integers could look like void myfunction(int *arr[], int size). what happens if a pointer in ...

arr1 is an array of 8 pointers to integers. int (*arr2)[8]; 1. arr2 is a pointer (the parenthesis block the right-left) to an array of 8 integers. int *(arr3[8]); 1. arr3 is an array of 8 pointers to integers. This should help you out with complex declarations. Here is...

They are readable and don't implicitly convert to pointers. They are not confused with non-standard extensions of built-in arrays. 它们的可读性好,而且不会隐式转换为指针类型。它们不会和内置数组的非标准扩展相混淆。 Example, bad(反面示例) ...
This example is a declaration of an array of structures. This array has 100 elements; each element is a structure containing two members. C Kopiér extern char *name[]; This statement declares the type and name of an array of pointers to char. The actual definition of name occurs elsewh...
