In C++ This exercise involves implementing the solution to the bounded buffer/readers and writers problem using threads. You will create a program that accepts four command line arguments: run_time (the length of time the program should run) buffer_size (number of slots in the bounded buffer) num_producers (number of producer threads) num_consumers (number of consumer threads) The program will create a thread for each producer and consumer. As each thread produces or consumes a data item, it will print its status. Example Output Here are some sample runs: Not enough arguments If not enough arguments are provided, the program should print an error message and exit. $ ./bounded_buffer Wrong number of arguments. Usage: bounded_buffer <run_time> <buffer_size> <num_producers> <num_consumers> $ Invalid argument If an argument is less than or equal to 0, the program should print a message and exit $ ./bounded_buffer 10 5 1 0 ./bounded_buffer 10 5 1 0 num_consumers…

// please don't copy from chegg in java: Use multithreading and thread synchronization to code an application simulating a bank deposit and withdrawal process. Set up an account containing an initial balance of $1000.00 for both of the two shared threads, Husband and Wife. When a thread makes a deposit in an account, the other thread must wait. If the account balance is $0.00, no withdrawals are permitted. Assume a deposit transaction requires 0.2 seconds to complete and a withdrawal transaction requires 0.5 seconds to complete. Generate random number 1 as deposit and 2 as withdrawal, respectively. Write a driver class MultiThreadAppt o test your application, repeat, and display the operations 50 times. Document all source code as required above.
Computer Science Using Java Write a program that opens up 2 threads of the same class. The threads say "I'm a thread".
using C language Write a program that creates an array of length 10, then creates 8 threads. should request entrance to their critical sections that is controlled through semaphores, read the values written in the array, and write it to the screen with the following format: "Consumer number - consumed item number-with the value-" And to a file named "Consumer activity", then exit the critical section, and repeat till the producers stop production. The total number of elements generated by the producer and consumed by the consumers should be 10,000,000 number
IN C LANGUAGE Please write a program to scan an integer number N entered by the user. Create 4 threads andassign them to find ALL prime numbers between 1 to N. NOTE: YOU MAY ASSUME 1 and 2 ARE PRIME
Course: Operating Systems write a multi-threadeddirectory copy program. The program will create destination directory and open thesource directory. Then for each file in the source directory it will create a thread. Thethread will copy file from source directory to the destination directory. At the end it willprint the number of files copied. Both the source and destination names will be passed ascommand line arguments. Sample execution is as follows:mtcopy.exe source_dir destination_dirCopied 8 files Note: The answer is availible on chegg.
Purpose of this assignment: To allow student to be able to implement a Java thread-based application by loading allowing user to perform a computation operation. Instruction: This is an individual assignment. You have to use Java thread to write a program that can perform two calculation functions concurrently. One of the function will generate a series of Fibonacci number sequence. The second function will calculate the result of factiorial function. This factorial function will allow the user to input a start number, end number and number of threads. Then, function will split into thread to perform the calculation. At the end, the function will merge the result of each thread calculation and display the result.
The Fibonacci sequence is the series of numbers 0, 1, 1, 2, 3, 5, 8, .... Formally, it can be expressed as: fib0 = 0 fib1 = 1 fibn = fibn−1 + fibn−2 Write a multithreaded program that generates the Fibonacci series using either the Java, Pthreads, or Win32 thread library. This program should work as follows: The user will enter on the command line the number of Fibonacci numbers that the program is to generate. The program will then create a separate thread that will generate the Fibonacci numbers, placing the sequence in data that is shared by the threads (an array is probably the most convenient data structure).When the thread finishes execution, the parent thread will output the sequence generated by the child thread. Because the parent thread cannot begin outputting the Fibonacci sequence until the child thread finishes, this will require having the parent thread wait for the child thread to finish.
