What does this code print?
int main()
{ auto p1 = make_shared(42);
auto p2 = p1;
cout << *p1 << endl;
cout << *p2 << endl;
(*p2)++;
cout << *p1 << endl; }
A. 424343
B. Does not compile (illegal)
C. 424242
D. Undefined behavior
E. 424243
Answers
The output of the code is: 424243
So, the correct answer is E.
The `auto p1 = make_shared(42)` statement initializes the p1 pointer with a shared_ptr to a dynamically allocated int of value 42.
The `auto p2 = p1` statement creates a new shared_ptr p2 which points to the same memory location as p1, and the reference count of the shared object is incremented by 1.
The `cout << *p1 << endl;` and `cout << *p2 << endl;` statements output the value of the int, which is 42, twice because both pointers point to the same location.
The `(*p2)++;` statement increments the value of the int to 43. Finally, `cout << *p1 << endl;` outputs the value of the int, which is 43, because both pointers point to the same memory location.
Therefore, the output of the code is option E: 424243.

Where are MAC addresses stored for future reference?
a. MAC cache
b. Ethernet cache
c. ARP cache
d. NIC
Answers
The MAC addresses are stored for future reference in the (C) ARP cache.
This cache is a table that maps the IP addresses to the corresponding MAC addresses on a network.
Whenever a device needs to communicate with another device on the network, it first checks the ARP cache to see if it already has the MAC address of the destination device.
If the MAC address is not found in the cache, the device sends out an ARP request to obtain the MAC address from the device with the corresponding IP address.
Once the MAC address is obtained, it is stored in the ARP cache for future reference.
This process helps to improve the efficiency of network communication by reducing the number of ARP requests that need to be sent out.

Smart contracts: With so much being said and published about blockchain, it appears that the technology may be misunderstood by the general public. They see it as a one-man band that can do everything, including enabling bitcoin, safeguard data, brew coffee, and more, rather than a technology.
Blockchain is a distributed, immutable database that simplifies the tracking of assets and the recording of transactions inside a business network. An asset may be tangible (such a home, automobile, sum of money, or plot of land) or intangible (intellectual property, patents, copyrights, branding). A blockchain network allows for the recording and trading of practically everything of value, lowering risk and increasing efficiency for all parties. Business depends heavily on information, which is why blockchain technology is significant. It is preferable if it is received promptly and accurately.Because it provides real-time, shareable, and fully transparent data that is recorded on an immutable ledger and only available to users of a permissioned network, blockchain is the perfect technology for delivering such information.
