I have a constant array of function pointers in code space and I an trying to declare a pointer variable to point to this array and then assign the array address to the pointer variable. The C51 compiler gives an error 213 for the assignment. Is there anything obviously wrong with what I...
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 ...

在VBA指针Pointer里提到了3个取地址函数,VarPtr、StrPtr、ObjPtr。 其中提到了我们只需要VarPtr函数,是可以获取StrPtr、ObjPtr返回的地址的。 在VARANT里,我们讲到了Variant这个类型,它可以保存任何的类型,通过它的一个转换,我们不就可以获取到数组的地址吗? 是的,我们只要把1个数组赋值给1个Variant,然后去读取Varian...
第七行,int *p = ia;若以數學角度,p和ia是相等的,而p是pointer,ia是array,所以推得pointer就是array,但C/C++並非如此,這個=是assignment的意思,也就是將array ia assign給pointer p,經過自動轉型後,將array ia第一個element的address assign給pointer p,這也是為什麼Pascal語系的assignment使用:=而非=,就是為...
