Two example files - “student1.txt” and “student2.txt” are given on BlackBoard along with this question. Each line represents a student. The first column is the student ID; the remaining columns are the scores. -1 represents an excused score.
Input: the input user should enter the name of the file and the number of exams for the given semester Output: Below is a sample I/O. Only the bolded numbers are the inputs provided by the user.
Enter the name of the file that has the scores of students: student1.txt Enter the number of scores for each student: 4
Let’s say if the input file of student scores looks like this:
15 51 55 50 52
25 80 -1 70 -1
23 53 -1 57 40
21 50 -1 49 50
The output file should look like this
ID=15 Avg=52 Grade=S
ID=25 Excused=2 Grade=I
ID=23 Avg=50.0 Grade=S
ID=21 Avg=49.7 Grade=U
Number of Grades of Type
SUI
211

I'm having trouble with the input and output of the files.
I know I have to ifstream inputfile and string it. What I am having a problem with is actually putting the information into the file.
I understand the -1 and how to cout everything, I am just not understanding how to put the information into the file so it can be brought up once the user inputs the txt file and the number of scores.
