There is an unknown type array pointer, how can you remove the data in the array

CodePudding user response:

Since the unknown type, how to take the data in the array?

CodePudding user response:

To analyze the data structure, reading, from the experimental data structure, can be read correctly,

CodePudding user response:

Can you give a example code

CodePudding user response:

This unknown group of pointer, how to remove the data, thank you guys

CodePudding user response:

Pointers to this unknown group and how to remove the data, thank everyone, hungry write wrong

CodePudding user response:

Since type unknown, you when it is what type, what type is forced to cast a pointer or it can be assigned to other types of pointer,
For example:
Void * x=0 x12345678 (void *).//the unknown type array pointer
Int * p=(int *) x;//plastic array pointer to unknown type array
Int a=p [1000];//reading group element

CodePudding user response:

Ah, the original is the Delphi, that is more simple,
Type
TIntArray=array [0.. 0] of integer;
Var
X: pointer;
P: TIntArray;
The begin
X:=pointer ($12345678);
P:=x;
Writeln (p [0]);
end;
