Create a Student Log File

Introduction

In this challenge, you will practice file handling skills by creating a student record log in a school management system. The goal is to write student information, including name, ID, and grade, to a text file using C++ and the std::ofstream library. You will be required to create at least three student records and handle file stream errors appropriately.

Create a Student Log File

In a school management system, efficiently storing student information is crucial. This challenge will help you practice file handling skills by creating a student record log.

Tasks

• Create a C++ program to write student records to a text file
• Use ofstream to write student information, see example below
• Store at least three student records in the file
• Include student name, ID, and grade for each record

Requirements

• Create the program in ~/project/student_log.cpp
• Use std::ofstream for file writing
• Name the output file students.txt
• Each student record must include:
  • Name (string)
  • Student ID (integer)
  • Grade (double)
• Write at least three student records
• Use proper file stream error handling

Examples

Compile and run the program to create the student log file:

g++ student_log.cpp -o student_log
./student_log

Example students.txt content:

cat students.txt

John Doe,12345,3.75
Alice Smith,67890,3.92
Bob Johnson,54321,3.50

Hints

• Use std::ofstream to open and write to the file
• Check if the file is successfully opened before writing
• Use << operator to write data to the file
• Separate record fields with a comma
• Remember to close the file after writing

Summary

In summary, this challenge requires you to create a C++ program that writes student records, including name, ID, and grade, to a text file named "students.txt". You will need to use the std::ofstream library for file writing and handle any file stream errors that may occur. The program should store at least three student records in the output file.
