Printing multiple lines
package main
import "fmt"
func main() {
fmt.Println(`1
2
3`)
}
FOR Loop
package main
import "fmt"
func main() {
i := 1
for i <= 10 {
fmt.Println(i)
i = i + 1
}
}
OR
func main() {
for i := 1; i <= 10; i++ {
fmt.Println(i)
}
}
Note : Other programming languages have a lot of different types of loops (while, do, until, foreach, …) but Go only has one that can be used in a variety of different ways.
IF - ELSE Statement
IF - ELSE
if i % 2 == 0 {
// even
} else {
// odd
}
IF -ELSE -IF
if i % 2 == 0 {
// divisible by 2
} else if i % 3 == 0 {
// divisible by 3
} else if i % 4 == 0 {
// divisible by 4
}
SWITCH Statement
switch i {
case 0: fmt.Println("Zero")
case 1: fmt.Println("One")
default: fmt.Println("Unknown Number")
}
