Introduction
In this challenge, you need to create a simple grade tracking system to efficiently manage student performance using Go maps. As a teaching assistant, you will be tasked with implementing various operations such as adding students, retrieving and updating grades, and printing the current student grades.
Manage Student Grades with Go Maps
As a teaching assistant, you need to create a simple grade tracking system to efficiently manage student performance using Go maps.
Tasks
- Create a map to store student names and their corresponding grades
- Add at least 5 students to the grade tracking system (Alice, Bob, Charlie, David, Eve)
- Print out all students and their current grades
Requirements
- Use the file
~/project/student_grades.gofor your implementation - Use a map with
stringkeys (student names) andintvalues (grades) - Grades should be between 0 and 100
Examples
Run the program:
go run student_grades.go
Example output:
Student Grades:
Alice: 85
Bob: 92
Charlie: 78
David: 95
Eve: 88
Hints
- Remember how to declare and initialize a map
- Use the
rangekeyword to iterate through map elements - Don't forget to use
:=for short variable declaration
Summary
In summary, this challenge requires you to create a simple grade tracking system using Go maps. You will need to implement operations such as adding students, retrieving and updating their grades, and printing the current student grades. The goal is to demonstrate your understanding of Go maps and their practical applications in managing student performance data.
