IN C++ you will simulate a simple multithreading application with a “producer and consumer” problem
Modify “Producer and Consumer Problem” from the lecture note so that it can use all buffer space, not “buffersize – 1” as in the lecture note. This program should work as follows: 1. The user will run the program and will enter two numbers on the command line.Those numbers will be used for buffersize and counter limit.2. The main program will then create separate producer and consumer threads.3. The Producer thread generates a random number through a random number generator function, inserts it into the buffer, prints the number, and increment counter.4. The Consumer thread goes to the buffer, takes a number in the proper order, prints it out, and increment counter.5. After the counter reaches its limit, both threads should be terminated and returned to the main.6. Main program terminates.
program and sample run should clearly show the implementation of subtasks through…

- Consider the following relations: Professor (profid: integer, name: varchar, salary: integer, age: integer, depid: integer)Department (did: integer, budget: integer, location: varchar, mgr eid: integer) Salaries range from $30,000 to $100,000, ages vary from 20 to 80, each department has about 20 employees on average, there are 10 locations, and budgets vary from $100,000 to $1 million. You can assume uniform distributions of values. For each of the following queries, what index would you choose to speed up the query? If your database system does not consider index-only plans (i.e., data records are always retrieved even if enough information is available in the index entry), how would your answer change?
