DESCRIPTION: (1) Write a program to read and format data for FOUR students. (2) Flag the academic status of each student: ON PROBATION -- when GPA < 2.0 HONORS -- when GPA >= 3.0 GOOD STANDING -- when neither honors nor probation. (3) Compute the arithmetic and weighted average GPA of the three students. INPUTS: (1) Input file: students.dat. (2) All the data for a student are on the same input line: ID Firstname Lastname CumHours GPA Example: 143841138 Edward Jones 112 2.52 411384112 Miser Frugal 67 1.99 118113428 Marilyn Sapp 31 3.828 943448138 Guess Who 112 2.23 813384212 Need Mercy 67 1.79 718116428 Flying High 31 3.57 OUTPUTS: (1) Output files: by standing: honors.dat, good_standing.dat, at_risk.dat One student record per line: ID Firstname Lastname CumHours GPA ID Firstname Lastname CumHours GPA (2) The program must terminate (exit(1);)and print the following message if the input file can not be opened: FATAL ERROR: can not OPEN file 'students.dat'. (3) A formatted report is displayed on the screen (sample shown below).

Open input file. 1.1 If the input file can not be opened, print termination message and terminate program. 2. Open the output files. 3. Set all the counts and sums to ZERO. 4. Display ACADEMIC STANDING REPORT headings. ----------------------------------------------------------- NOTE: The following steps 5-9 must be repeated 4 times. ----------------------------------------------------------- 5. Read input data for one student from input file. 6. Write student data to the Standing Report. 7. Increment the overall number of students. 8. Add the GPA to the overall GPA sum. 9. Determine the academic standing of student, and based on classification: 9.1 Write student data to required output file 9.2 Count the student for the classification (honors, at-risk, good-standing) 9.3 Add the GPA to sum for the classification ----------------------------------------------------------- NOTE: The following steps 10-14 complete the process. ----------------------------------------------------------- 10. Display Standing Report Footer. 11. Calculate the average GPA for each classification: ZERO if no students in the classification. 12. Write to Standing Report the overall average GPA, then avg GPA for at-risk, good-standing, and honors. 13. Write to Standing Report the count of students: overall, at-risk, good-standing, honors. 14. Close input and output files. ====================================================================== OUTPUT LAYOUT ANALYSIS data type float long int int string string precision 2 - - - - - align R R R R L L width 4 9 4 5 16 18 ---- --------- ----- ---------------- ------------------ | | | | | | | | | | 1111bb222222222bb44444bbb5555..........55bb666666.........666 ==== ========= ===== ================ ================== GPA StudentID Hours Student_Name Academic Standing ==== ========= ===== ================ ================== 2.52 143841138 112 Jones, Edward GOOD STANDING 1.99 411384112 67 Frugal, Miser AT RISK 3.83 118113428 31 Sapp, Marilyn HONORS ==== ========= ===== ================ ================== string float data type - 3 precision left right justification ---------- 23 ---------- 5 - field width | | | x.xxx 2.779 = Average Student GPA
