循环语句

for 循环语句 i 小于10  

for i :=0; i < 10; i++;{
   fmt.Printf("sum: %v\n",i)    
}

 

for死循环

for {
fmt.Println(i)  
}

判断语句

if err !=nil{
    fmt.Println(err ) 
} 

if name =="zhangsan"{
    fmt.Println(name) 
} 

if sum >=100{
    fmt.Println(sum) 
} 

if sum <=100{
    fmt.Println(sum) 
} 

switch 判断语句

var sum = 10
switch sum {
    case 1:
       fmt.Println(sum)
    case 3:
       fmt.Println(sum)
    case 5:
       fmt.Println(sum)
    case 8:
       fmt.Println(sum)
    default:
       fmt.Println(sum)    
}
