"Create a flowchart for an Academic Evaluation System. The system allows a user to input a student’s Name, Roll Number, and Marks for 5 subjects (0–100). Include the following steps:

Start – Begin the process.

Input Details – Enter Student Name, Roll Number, and Marks for 5 subjects.

Validate Inputs – Check that Name and Roll Number are not empty and marks are between 0 and 100.

If invalid, show error and go back to Input Details.

Choose Evaluation Mode – Select either:

Result Based on Percentage

Result Based on CGPA

Calculate Total and Percentage – Add all marks and compute percentage.

Calculate CGPA – Compute CGPA as percentage ÷ 10.

Assign Grade – Use rules:

90+ → A

75–89 → B

60–74 → C

40–59 → D

<40 → F

Determine Result – If mode is:

Percentage → PASS if percentage ≥ 40 else FAIL

CGPA → PASS if CGPA ≥ 4.0 else FAIL

Display Student Record – Show Name, Roll, Total, Percentage, CGPA, Grade, and Result.

Option to Add Another Student or Delete Record – Loop back to Input Details or End.

End – Stop the process.

Use standard flowchart symbols: oval for Start/End, parallelogram for input/output, rectangle for processing steps, and diamond for decisions."
