This question is way to long I don’t even understand what your asking
Answer:
184
Explanation:
Given the codes
- int cost = 82;
-
- if (cost < 100)
- {
- cost = cost + 10;
- }
-
- if (cost > 50)
- {
- cost = cost * 2;
- }
-
- if (cost < 100)
- {
- cost = cost - 20;
- }
The initial value of cost is 82.
The if condition in Line 3 will pass and therefore cost = 82 + 10 = 92
The if condition in Line 8 will pass and therefore cost = 92 * 2 = 184
The if condition in Line 13 will fail l and therefore the if block will be skipped.
At last, the we get cost = 184.
Answer:
Answer explained below
Explanation:
Yes, you can let Set-uid program that is owned by root to run your code instead of /bin/ls but it has it's own drawbacks and is actually not safe.
As you can not rely on that since some of the shells if different from the ruid drop an euid which is actually not safe.
execl("/bin/ls", "ls",(char *)0);
run this under your main program.
Since it can have a root previlege,
-$ cd /tmp/
/tmp$ sudo su
:/tmp# gcc -o system system.c
:/tmp# chmod u+s system // changing file permissions
:/tmp# exit
exit
:/tmp$ cp /bin/sh /tmp/ls
:/tmp$ ./system
<u>Steps:
</u>
1. The first thing you need to do is copy /bin/sh to /tmp.
2. After copying /bin/sh to /tmp set a new name ls but make sure your sh ->.zsh.
3. Set PATH to current directory. /tmp.
4. Compile
5. Run the program system and you can get your root previledge.
Now, with the above exmaple if you change /bin/sh soo that it points back to /bin/bash and repeat all the previous steps, you will not be able to get your root previledges.
Answer: Analyze the organization's strategic plan
Explanation:
The initial step in the information system is to first analyze the strategic plan of the organization so that we can easily identify the main objective and challenge.
It is basically archived by enlisting the particular objective and function in the planning of information system in the organization.
All the remining option are involve in the remaining step of the information system planning not in the initial step.
Therefore, analyze the organization's strategic plan is correct as it is the first step of the information system planning.
Answer:
Dubbed “El Capitan,” the supercomputer is part of the Exascale Computing Project, a DOE effort to increase computing power so that the department can run highly advanced simulations and modelling of the United States' nuclear arsenal. These simulations help alleviate the need for underground testing.
