Question

You have been provided with a QTCreator project called Project12 _ Student. Open the project in QTCreator and make the necessary changes to the main.cpp and infostation.cpp / h files.

The class InfoStation contains 3 public methods namely : float getTemp ( ) ; - Returns a random temperature between 1 and 100 ( In float format )

float getHour ( ) ; - Returns a random hour between 1 and 24 ( In float format )

string getDay ( ) ; - Returns a random day between 1 and 10 ( In string format )

Using the class InfoStation fill the provided multidimensional array named WData[10][4] with values in the main function. The first 3 columns in WData should contain a temperature a hour and a day generated using the InfoStation class.

Column 1 - temperature retrieved using getTemp ( ) from the InfoStation class.

Column 2 - hour retrieved using getHour ( ) from the InfoStation class.

Column 3 - day retrieved using getDay ( ) from the InfoStation class.

Column 4 - no value at this stage will be calculated by calcPower ( ... )

This should be repeated for each of the 10 rows.

After populating the multidimensional array with values create and call the function calcPower ( ... ) .

The calcPower ( ... ) function will receive the array WData as parameter and calculate the solar power that would have been produced on the day. The solar power value is calculated by multiplying the days temprature with the the ( hour / 2 )

The calculated value should be stored in the 4th column of WData

Introduction

Program description :

The program contains the three files

1.Header file : infostation.h
2.Implementation file : InfoStation.cpp
3. Tester file : Tester.cpp

The infostation header file contains the methods getTemp ,getHour and getDay declarations.

The InfoStation implementation file contains the method implementations

In the main method of Tester.cpp file, declare a 2D array WData of 10x4 size. Fill the random values for temp, hour, and day values. Then, calculate the power using the method, calcPower .Display the results of WData before and after the method,calcPower calling.
