Write a program that reads a sequence of scores from a file and outputs the highest score. File name is input by the user (using cin >>) The program uses a function getHighscore() to read the input from file and determine the highest score. This function may throw two exceptions (depending on the situations):

FileIOError, if the file can not be opened
EmptyFileError, if the file includes no scores
Both exceptions must be defined as separate classes. These two classes can be empty or inherit from existing exception class, like run_time error class.

You can assume that, if a file includes scores, they are all positive integers and separated by spaces.

input1.txt is empty

input4.txt: 30 23 14 28 41

main. cpp

#include
#include
#include

using namespace std;

//Add exception classes

//Define getHighscore function

int main()
{
string filename;
cin >> filename;

try
{
int highscore = getHighscore(filename);
cout << "The high score is " << highscore << endl;
}
catch(/*catch FileIOError*/)
{
cout << "Could not open the scores file.\n";
}
catch(/*catch EmptyFileError*/)
{
cout << "The file is empty.\n";
}
return 0;
}
