Void pointer and void pointer

Void pointer and void pointer
Void pointer indicates that the data type pointed to by this pointer in memory must be specified by the user.


For example, the pointer returned by the memory allocation function malloc is the void * type,


When using this pointer, the user needs to perform forced type conversion, that is, explicitly indicating the type of data that the Pointer Points to in the memory.


(Int *) malloc (1024) indicates that the void * pointer returned by malloc is forced to point to memory for int-type data.
