Memory Acccess

[Ambika]

Hi,

How to access memory without using pointers?

[matsp]

What do you ACTUALLY want to do - this question is like the guy with a punctured car tyre asking "How do I loosen a wheel-nut?"

You are obviously wanting to do something "more" than accessing memory. Describe a bigger picture, and we can probably help.

What is the reason you want to "access memory without using a pointer", you alergic to pointers, or some such?

Essentially, most memory access happens trough a pointer in C, but it depends a little on the scenario.

I dont think its a vague question.

Without the knowledge of pointers i would have never asked this question.

What i want to do is to access some memory location without using pointers and put some value at that location. You can print the value or can do whatever with that value.....


If you still feel its an irrelavent question i dont have further explanation to get answer from you

You said it depends a little on the scenario.. If you have come accross such can you explain me?

If you don't want to put a bunch of restrictions on what memory you want to modify, then a pointer is the only way to modify memory arbitrarily - or you could of course write some assembler code to access the memory - but that's only avoiding a pointer in the same way a drug-dealer escapes a life-sentence with a clever lawyer: on a technicality. You are still using a pointer in this case, but not a C pointer.

Is this a quiz question ?

There are some answers, which can be used in some circumstances, but it isn't pretty.
