create a system call called getcount() to xv6, which, when passed a valid system call number, returns the number of times the reference system call was invoked by the calling process.

This "Math Skill Builder" programming project will assess a few basic mathematics skills and includes a simple programmed interface to generate three Math skill builder problem sets in the area of arithmetic, geometry and statistics. Although the interface includes statistics, the problem sets are not generated and maybe used for an extra credit portion of this project. The program interface for each Math skill builder set generates four problems in a series that make up the set and uses randomly generated numbers in the range of 1 to 10, stored as double values.

Use the started code provided with QUEUE Container Adapter methods and provide the implementation of a requested functionality outlined below.   This program has to be in c++, and have to use the already started code below.   Scenario: A local restaurant has hired you to develop an application that will manage customer orders.  Each order will be put in the queue and will be called on a first come first served bases. Develop the menu driven  application with the following menu items: Add order Next order Previous order Delete order Order Size View order list View current order Order management will be resolved by utilization of an STL-queue container’s functionalities and use of the following Queue container adapter functions: enQueue:  Adds the order in the queue  DeQueue:  Deletes the order from the queue Peek: Returns the order that is top in the queue without removing it IsEmpty: checks do we have any orders in the queue Size:  returns the number of orders that are in the queue…
