Hi
This question is related to Systems Programming
Problem-
Create a linked list with 5 nodes -
Size of nodes 10K,20K,30,40,50K
Assume node1 and node3 load with program 1 and 2 store the new program in the following size 60K.
Using Best fit and first fit method.
My doubts-
1-How do u make a program access data in another program.( I know global vars come in somewhere but don't know how to link the programs )
Any sort of help will be appreciated!
cheers!
Your question makes me ask two more questions to clarify what you want to do.
1. What do you mean by a program. Is a program the same as an executable?
2. What system is this supposed to run on? What compiler are you using?

Compilers can produce warnings - make the compiler programmers happy: Use them!

I guess a program is code that is stored as a separate file and can be compiled independently.
The system is Unix GCC compiler.
thanks for ur interest.
Well, if the "executable file" is a separate process, then to share it with any other process, you will need to use something called "shared memory".
Here's a Linux link that shows some variants of shared memory; other Unix variants may have other implementations [although these two are the most common ones]:

Are you actually supposed to learn about shared memory, or is this just a really bad word problem for the knapsack problem? Somehow the latter seems more likely to me.
