Like integers that you could decide to interpret as a memory address and thus use like a char * (char pointer). As in machine code, basically. C made pointer arithmetics work like array indexing. Also, the combined dereferencing and member lookup operator (->). |

That's actually a dud. The motivation was likely caused by the silly choice of the dereference operator being unary/prefix, requiring parentheses in (*ptr).memb.
Compare with Pascal's ptr^.member where no parentheses are required.
But ptr.memb can just work as well as value.memb. The operator statically knows whether the left operand is a pointer to a struct/union or a struct/union value.
