Go Learning notes: if Else condition judgment

This is a creation in Article, where the information may have evolved or changed.

The conditional judgment structure of Go language is also very simple.

package mainimport  "FMT" Func main ()  {    //  Basic examples      if 7%2 == 0 {        fmt. Println ("7 is even")     } else {         fmt. Println ("7 is odd")     }    //  only if condition conditions      if 8%4 == 0 {        fmt. Println ("8 is divisible by 4")     }    //  The IF condition can contain an initialization expression, the variable in the expression     //  is the local variable of this conditional judgment structure     if num  := 9; num < 0 {        fmt. Println (num,  "is negative")     } else if num < 10  {      &nbsP; fmt. Println (num,  "Has 1 digit")     } else {         fmt. Println (num,  "has multiple digits")     }}

In the conditional judgment structure, the parentheses () on both sides of the condition can be omitted, but the braces {} on either side of the conditional execution statement block are not available.

The output result is

7 is Odd8 was divisible by and has 1 digit

There is no ternary expression "?:" in Go, so you can only use conditional judgment statements.
