The continue statement in the Go language is a bit like the break statement. But continue instead of jumping out of the loop, skip the current loop to execute the next loop statement.

In for loop, execute continue statement triggers for executionof incremental statements.

In multiple loops, you can use labels label mark one’s mind continue cycle.

2.27.1. Grammar #

continue syntax format is as follows:

continue; 

continue statement flow chart is as follows:

2.27.2. Example #

In variables a equal to 15 skip this loop and execute the next loop:

Example #

package main import "fmt" func main() { /* Define local variables */ var a int = 10 /* For loop */ for a < 20 { if a == 15 { /* Skip this loop */ a = a + 1; continue; } fmt.Printf("The value of a is: %d\\n", a); a++; } } 

The execution result of the above example is:

The value of a is: 10 The value of a is: 11 The value of a is: 12 The value of a is: 13 The value of a is: 14 The value of a is: 16 The value of a is: 17 The value of a is: 18 The value of a is: 19 

The following example has multiple loops that demonstrate the difference between using tags and not using tags:

Example #

package main import "fmt" func main() { // Do not use tags fmt.Println("---- continue ---- ") for i := 1; i <= 3; i++ { fmt.Printf("i: %d\\n", i) for i2 := 11; i2 <= 13; i2++ { fmt.Printf("i2: %d\\n", i2) continue } } // Using tags fmt.Println("---- continue label ----") re: for i := 1; i <= 3; i++ { fmt.Printf("i: %d\\n", i) for i2 := 11; i2 <= 13; i2++ { fmt.Printf("i2: %d\\n", i2) continue re } } } 

The execution result of the above example is:

---- continue ---- i: 1 i2: 11 i2: 12 i2: 13 i: 2 i2: 11 i2: 12 i2: 13 i: 3 i2: 11 i2: 12 i2: 13 ---- continue label ---- i: 1 i2: 11 i: 2 i2: 11 i: 3 i2: 11

最近几年来,地理信息系统无论是在理论上还是应用上都处在一个飞速发展的阶段。 GIS被应用于多个领域的建模和决策支持,如城市管理、区划、环境整治等等,地理信息成为信息时代重要的组成部分之一; “数字地球”概念的提出,更进一步推动了作为其技术支撑的GIS的发展。 与此同时,一些学者致力于相关的理论研究,如空间感知、空间数据误差、空间关系的形式化等等。 这恰好说明了地理信息系统作为应用技术和学科的两个方面,并且这两个方面构成了相互促进的发展过程。
