You are a high school student learning about computers and how to build them. As a class project, you have built a new computer. You power on your computer and begin to configure the system.

In the U.S. fuel efficiency of cars is specified in miles per gallon (mpg). In Europe it is often expressed in liters per 100 km. Write a MATLAB user- defined function that converts fuel efficiency from mpg to liters per 100 km. For the function name and arguments, use Lkm-mpgToLpkm (mpg). The input argument mpg is the efficiency in mi/gl, and the output argument Lkm is the efficiency in liters per 100 km (rounded to the nearest hundredth). Use the function in the Command Window to:________. (a) Determine the fuel eficiency in liters per 100 km of a car whose fuel effi- ciency is 21 mi/gal. (b) Determine the fuel efficiency in liters per 100 km of a car whose fuel effi- ciency is 36 mi/gal.

Heinrich Koch is a second-year college student. Last semester his best friend had his laptop stolen. The laptop was an old computer that he planned to replace soon, but the greatest loss was his data: he had not performed a backup and all his data was lost. Heinrich himself does not perform data backups but knows that he needs to do that on a regular basis. He has decided to use an online backup service that will automatically back up his data whenever it changes. Evaluate and compare reviews of online backup services. Consider iDrive, Carbonite, Acronis True Image, BackBlaze, and others you might find in your research. Recommend a service that you consider the best solution for Heinrich. Discuss your reviews and mention speed, security, and features in your recommendation.

Design a class named Employee. The class should keep the following information in member variables:Employee nameEmployee numberHire DateWrite one or more constructors and the appropriate accessor and mutator functions for the class.Next, write a class named ProductionWorker that is derived from the Employee class. The ProductionWorker class should have member variables to hold the following information:Shift (an integer)Hourly pay rate (a double)The workday is divided into two shifts: day and night. The shift variable will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write one or more constructors and the appropriate accessor and mutator functions for the class. Demonstrate the classes by writing a program that uses a ProductionWorker object."Now I have written out the program, it compiles without errors. However, when I run it It asks the first question "Employees name" after input it errors and closes itself down. Can anyone find where in my code it is causing it to do this please? To be clear, I am not asking for someone to write the program, I have already done this, just need to know why it compiles but does not run all the way through. Thank You!#include #include #include using namespace std;class Employee{private: string employeeName; int employeeNumber; int hireDate;public: void setemployeeName(string employeeName); void setemployeeNumber(int); void sethireDate(int); string getemployeeName() const; int getemployeeNumber() const; int gethireDate() const; Employee();{
