break Statements can end for、switch and select Code block for .break Statements can also be tagged after statements **（ In the following code BreakTag、BreakTag2）**, Indicates to exit the code block corresponding to a tag , Label requirements must be defined in the corresponding for、switch and select On the code block of .

	BreakTag:
		for i := 0; i < 5; i++ {
    
			BreakTag2:
				for j := 0; j < 4; j++ {
    
					fmt.Println(i, j)
					switch i {
    
						case 1:
							break BreakTag
						case 3:

continue Statement can end the current loop , Start the next iteration of the loop , Only in for Use in cycle . stay continue When you add a label after a statement , Represents the loop corresponding to the start tag

	ContinueTag:
		for i := 0; i < 5; i++ {
    
			ContinueTag2:
				for j := 0; j < 4; j++ {
    
					fmt.Println(i, j)
					switch i {
    
						case 1:
							break ContinueTag
						case 3:
							break ContinueTag2
					}
