Question

Go (programming language)

Create a map that uses a string representing a course code as key. The value in the map needs to be a structure with basic information about the course. The following main routine:

import "fmt"
    
// Define a suitable structure 

func main() {
        // Create a dynamic map m

        // Add the courses CSI2120 and CSI2110 to the map 

        
        for k, v := range m {
                fmt.Printf("Course Code: %s\n", k)
                fmt.Printf("Number of students: %d\n", v.NStudents)
                fmt.Printf("Professor: %s\n", v.Professor)
                fmt.Printf("Average: %f\n\n", v.Avg)
        }
}

must print:

Course Code: CSI2110
Number of students: 186
Professor: Lang
Average: 79.500000

Course Code: CSI2120
Number of students: 211
Professor: Moura
Average: 81.000000

Answer 1

package main
import "fmt"
  
// Define a suitable structure
type course struct {
courseCode string
NStudents int
Professor string
Avg float64
}

func main() {
// Create a dynamic map m
var courses = map[string]*course{}

// Add the courses CSI2120 and CSI2110 to the map
courses["CSI2110"] = &course{courseCode: "CSI2110",NStudents: 186,Professor: "Lang",Avg: 79.5}
courses["CSI2120"] = &course{courseCode: "CSI2120",NStudents: 211,Professor: "Moura",Avg: 81}
  

  
for k, v := range courses {
fmt.Printf("Course Code: %s\n", k)
fmt.Printf("Number of students: %d\n", v.NStudents)
fmt.Printf("Professor: %s\n", v.Professor)
fmt.Printf("Average: %f\n\n", v.Avg)
}
}
