pointer auf variable c

p1 and p2 are pointers: they store address of variable & (like in &a): returns address of a variable * in declaration (like in int *p1): declare pointer to a variable (here to a int variable) * in expression (like in *p1 = 25): access to value stored at address stored in pointer; You can see different addresses and values : This is somewhat analogous to a hotel.

The content of a can be obtained using pa.This is called dereferencing a pointer.

Maybe it would be better to remove the comments after BTW when visualizing address values, it's customary to start the addresses at large numbers, like 1000, 1001, 1002 etc so their values won't be confused with data. A pointer to a pointer is a form of multiple indirection, or a chain of pointers. A pointer variable is a variable that contains an address, usually the address of another variable. But in C# pointer can only be declared to hold the memory address of value types and arrays. C# supports pointers in a limited extent. For example, the following declaration declares a pointer to a pointer of type int −When a target value is indirectly pointed to by a pointer to a pointer, accessing that value requires that the asterisk operator be applied twice, as is shown below in the example −When the above code is compiled and executed, it produces the following result −
