In a mailbox based message passing system, a process is not put in a waiting queue but receives an error signal upon sending to

a full mailbox. Similarly, a process is not put in a waiting queue but receives an error signal upon trying to receive from an empty mailbox. Then, the process will try its sending or receiving operation repetitively until it succeeds. Does this approach suffer from race conditions?

Answer:

Yes.

Explanation:

Race condition can be described as a situation where at any time there are two or more processes or threads operating concurrently, there is potential for a particularly difficult class of problems. The identifying characteristic of race conditions is that the performance varies depending on which process or thread executes their instructions before the other one, and this becomes a problem when the program runs correctly in some instances and incorrectly in others. Race conditions are notoriously difficult to debug, because they are unpredictable, unrepeatable, and may not exhibit themselves for years.

Hitman42 [59]

Answer:

The answer is "a1 and a2 is an array of pointers".

Explanation:

In this question, A collection of pointers refers to an array of elements where each pointer array element points to a data array element. In the above-given statement, the two-pointer type array "a1 and a2" is declared that holds the same size "8" elements in the array, and each element points towards the array's first element of the array, therefore, both a1 and a2 are pointer arrays.

When troubleshooting firewalls, which of the following is not something you should do after you attempt a fix?
mart [117]

Answer:

a. make multiple fixes.

Explanation:

When we are troubleshooting firewalls we should not make multiple fixes after attempting a fix because it will not be beneficial for the security purpose.

We can repeat the failure after attempting the fix because we can fix it but a person with right mind won't be doing that.

We can test after each attempt that it is working properly.

We can also  reverse or undo the solution failures after making a fix.

I need help with Python. The first image is the code and the 2nd is the output.
Gekata [30.6K]
The issue arises because the string you are trying to print is not a string, rather a float value. Item1, item2 and item3 are strong values (if you type some alphabets in it and not just numbers), but itemonecost, itemtwocost, and itemthreecost are explicitly type casted to float. In line 22, 23, and 24 you’re trying to print a float, by adding it with the string. One cannot add numbers to string. Rather you can type cast the itemcost to string while printing.

Add str(itemonecost) instead of itemonecost in print statement. Do this for other float variables too.

However do note that there are multiple ways to correct this issue, and I’ve just pointed one out.
