Three ways to if,swich,for the Go language

A go language for loop has 3 forms, only one of which uses semicolons.

Package Main

InPort

"FMT"

)

FNNC Main () {

For i:=0;i<5;i++{

Fmt.println ("%d,i")

}

}

Dead loop

Func Main () {

for {

Fmt.println ("Dead Loop")

}

}

Add a loop

Func Main () {

I:=5

For i>0{

I=i-1

Fmt.println ("%d,i")

}

}

The switch of Go is very flexible. An expression does not have to be a constant or an integer.

Func main (a int) {

    Digital    Switch A {case    1:        FMT. Println ("1")
    Case 2:        FMT. Println ("2") Case    3:        FMT. Println ("3")    }}
If statement

If x > 0 {    return y} else {    return x}

If Boolean expression   1{/* executes when Boolean expression 1 is true */if Boolean expression 2 {/* isexecuted when Boolean expression 2 is true */}
                        
                         }
                        
Nested Else If...else statements in an if statement

PackageMainImport "FMT"Func Main() { /* Define Local Variables */ VarAInt = 100 VarBInt = 200 /* Judging condition */ IfA== 100 { /* If condition statement is true */ IfB== 200 { /* if condition statement true execution * / Fmt. Printf (  } } Fmt.printf ( "a value:%d\n" , a  Fmt. Printf ( "B value:%d\n" , b ) ; }             /span>
