> Only the ISO C language is allowed, declare C array and then show us how do you validate the accesses with the index operator. Who said anything about arrays? Let me refresh what was said, and what you claimed. What was said: > what do you think apl and oberon can express that C cannot ? What you claimed > Bounds checking by default. Are you seriously saying that you did not claim that bounds checking cannot be expressed in C? Because that is all this boils down to - my reading of that was that you claimed that bounds checking is an example of a thing that "apl and oberon can express that C cannot ? " > Only the ISO C language is allowed, declare C array and then show us how do you validate the accesses with the index operator. No one made this claim so there is no point in doing what you asked. > As second exercise, show us how a function call using pointer + length, validates that the lengh into the pointer region is a valid length for the memory region total size. No one claimed this either. The specific claim is that it is possible to express bounds checking in C.
