SUBSCRIBEFunctions
- Functions are the proper way of developing a very long code and using various shortcodes
- Functions handle a bundle of code and you can call a function in your main code just by giving the inputs and it’ll process the input accordingly returns the desired output.
//Sample code is as follows
func eatTacos() {
fmt.Println("Yum!")
}
func main() {
//calling the function here
eatTacos() //prints Yum! here
}
- Functions with return type and scope example is as follows
func computeMarsYears(earthYears int) int {
earthDays := earthYears * 365
marsYears := earthDays / 687
return marsYears
}
func main() {
myage := 23
//returning marsYear with myAge as input
myMartianAge := computeMarsYears(myAge)
fmt.Println(myMartianAge)
}
- Functions with multiple return type can be used as follows
func GPA(midtermgrade float32, finalGrade float32) (string, float32) {
averageGrade := (midtermGrade + finalGrade) / 2
var gradeLetter string
if averageGrade > 90 {
gradeLetter = "A"
} else if averageGrade > 80 {
gradeLetter = "B"
} else if averageGrade > 70 {
gradeLetter = "C"
} else if averageGrade > 60 {
gradeLetter = "D"
} else {
gradeLetter = "F"
}
return gradeLetter, averageGrade
}
