Write a calculator program to compute math equations using pipes - program needs to fork() as many times as needed and use pipes to communicate to children. Equation specified in the first line of the data file will determine this setup. Once the setup is done, parent task reads the data from the data file and pumps into various pipes in parallel and results come back to main task using another pipe. All tasks use standard input stream 0 to read the first argument, use stream 3 to read 2nd argument and use standard output stream 1 for output. Main task uses the pipe stream numbers directly since it needs standard I/O streams to communicate with the user.

17. implement the jvm dload instruction for the mic-2. it has a 1-byte index and pushes the local variable at this position onto the stack. then it pushes the next higher word onto the stack as well

Write a car class having two private member variables called tank and speed. write public methods called pumpgas and gofast. the method pumpgas gets an integer for gas that must be pumped. that value needs to be added to tank (no more than 20 gallons). it must return the amount of gas that is purchased ($4 per gallon). the method gofast should increase the speed by 5 each time it is called.write a constructor for the above class that initialized both variables to zero.write a tostring to display both the tank and speed when the car is printed.modify the car class to implement the interface comparable and an interface called carinter having the public methods in carinter.write the main program to create an array of size 5 of type car. create 5 car objects having each location of the array to refer to one of the cars. test the pumpgas, gofast, equals method on the array items. write an enhanced loop to print all the car values (using a tostring written last time).write a generic method to find the minimum of four items. pass int, double, char, string and car objects to test this method.
