Create two triangle classes, one where the internal properties are stored on the stack and one where the internal properties are stored on the heap.  Each triangle should have a base, height, and a function that returns the area.

Triangles 1:  Create a vector of triangles where everything is stored on the stack. 

Triangles 2: Create a vector of triangles where everything is stored on the heap.

Triangles 3:  Create a vector where the items in the vector are stored on the stack, but the individual items have some data on the heap.

Triangles 4: Create a vector where the items in the vector are stored on the heap, but the individual items use no dynamic memory.

Note:  Think about what version of the triangle you should use for each scenario and make sure you do not have any memory leaks.

Perform a program written in ASSEMBLY 486, on Linux, with the requirements indicated below

Requirements:
The program should ask the user for the name of the file to be read.
The program opens a text file and performs one of the following operations:
1- Read the contents of the file, change the lowercase to uppercase letters, and print the result on the screen
2-Read the contents of the file, change capitals to lowercase, and print the result on the screen
3-Read the contents of the file, eliminate punctuation characters, and print the result on the screen
4-Read the contents of the file, eliminate the figures, and print the result on the screen
5-Read the contents of the file, eliminate all letters, and print the result on the screen
6-Read the contents of the file, leave only the punctuation marks, and print the result on the screen

The previous options must be displayed on the screen and the user chooses the desired option.
After executing the user’s request, the program again asks for an option.
There must be an option to exit the program.

Objectives:
To install and configure a SIP based IP-telephony server.
To be introduced on some telephony features an IP-PBX can provide.

2- Configure, connect and test a SIP based soft phone to the installed PBX.
3- Implement the following features that the PBX can provide:
a- Hunt group in ring all mode with three members.
b- Interactive voice response IVR with two levels menu options.
4- Use the PBX built-in SIP trace to log a completed SIP call trace and a failed SIP
phone registration request.
Submission Requirements:
1- An implementation report listing the, PBX network configuration configured
admin users names and passwords, configured extensions list and ring groups.
Also the report should include the requested SIP trace logs.
2- A live demonstration and presentation on the configured PBX; during this
demonstration an individual evaluation will take place.

Required Tools:
1- TrixBox 2.8.04
Trixbox CE is an easy to install, VOIP phone system based on the Asterisk PBX.
Trixbox is designed for home or office use. Trixbox CE includes CentOS linux,
mysql, and all the tools needed to run a business quality phone system.

2- Virtual box
VirtualBox is powerful Cross-platform Virtualization Software for x86-based
systems. “Cross-platform” means that it installs on Windows, Linux, Mac OS X
and Solaris x86 computers. And “Virtualization Software” means that you can
create and run multiple Virtual Machines, running different operating systems, on
the same computer at the same time. For example, you can run Windows and
Linux on your Mac, run Linux and Solaris on your Windows PC, or run Windows
on you Linux systems.

PLEASE EXPLAIN THE FOLLOWING OPERATING SYSTEMS QUESTION AND SOLUTION TO THE QUESTION IF IT IS THE RIGHT SOLUTION.

Consider an index-based file system with the inode containing 64 indexes, 1 indirect index pointing to a disk block containing an array of direct indexes, and 1 2-level index in the usual way. Assume that each index takes 4 bytes.

What is the maximum file size under this arrangement, if a disk block is 1024 bytes? Explain how do you compute this maximum size.

Solution:
An indirect block has 1024 bytes * 1 index/4 bytes = 256 pointers
So a file has at most 64 + 256 + 256*2 blocks and (64 + 256 * 256^2) * 1024 bytes.

How many disk accesses does it take to read one disk block at location 3000321 within a file, assuming no caching. Justify your answer.

Solution:
Block 3000321 is block number 2930, which means we have to read the inode, the 2-level index, a direct index, and the data block. 4 reads.

(i) what is the problem,
(ii) why it is important, (iii) why is it hard, (iv) why older approaches are not enough, (v) what is
key idea and why it works (a list of at least three key points), (vi) what might be missing and how
can we improve this idea (a list of at least three key points), (vi) an evaluation as to whether the
paper supports its claims, and (vii) possible next steps of the work presented in the paper. T
