The purpose of this program is to decide the final grades for a class.
There are five tests.  The lowest score will be dropped.

The rest of the four tests will be counted as equal weights for the semester average.
The grade is assigned as 'A' if the semester average >= 90;
'B' if the semester average is in the interval [80, 90);
'C' if the semester average is in the interval [70, 80);
'D' if the semester average is in the interval [60, 70);
'F' if the semester average is in the interval [0, 60);

Declare a class, StudentRecord, which has 4 data members as
name,
an array of 5 integers for scores,
average,
grade.

The class also has the following methods:

• Constructor.
• FindMin function to return a minimum integer out of five integers to caller.
• FindAvg function to find the average after dropping the lowest score and store it in average box.
• AssignGrade function to assign a grade.
• PrintResult function to print name, average, grade.

Create a main function to repeat the following jobs 8 times:
1. read data file one line at a time;
2. declare an object with the initial value from data file;
3. call the methods to print the name, average, and grade as below.
