c1234500   91.5	Enter the file name: score3.txt	Enter the file name: score.txt
c1234501   83		score.txt does not exist.
c1234502   96	There are 8 record in the file
c1234503   63.5	The average of the scores is 85.5	Enter the file name: score.dat
c1234504   82		score.dat does not exist.
c1234506   78	Student ID score Grade standing
c1234507   95	c1234500    91.5    A   above	Enter the file name: score4.txt
c1234510   95	c1234501    83.0    B   below
	c1234502    96.0    A   above	There are 3 student records.
score4.txt	c1234503    63.5    D   below	The average score is 90.2
C5432101  95	c1234504    82.0    B   below
c5432102   83.5	c1234506    78.0    C   below	Student ID score Grade standing
c5432103   92	c1234507    95.0    A   above	C5432101    95.0   A   above
	c1234510    95.0    A   above	c5432102     83.5   B   below
		c5432103     92.0   A   above
	c1234502 have the highest score of 96
		C5432101 have the highest score of 95

REQUIREMENTS:-

 

1) Print the purpose of the program.

2) Your program must read an input file name interactively.

3) If file does not exist. print error message and keep asking the user to enter another file name.

4) Your program should read and count student records from the file until the end of file.

5) Your program will find and print the average score, the number of students processed
