Go – For Loop Array Arrays are fixed-length sequences of elements of the same type. Using a For Loop, you can efficiently process each element of an array. In this tutorial, we will provide practical examples
strArray := []string{"a", "b","c"} //字符串数组 for i,v := range strArray { fmt.Println(fmt.Sprintf("下标为:%d 值为:%s", i,v)) } } 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 输出结果 下标为:0 值为:a 下标为:1 值为:b 下标为:2 值为:c 1. 2. 3. 二、循环控制语...

for范围的迭代通常适合于在数组或切片上读取或迭代许多数据(Go中的切片表示与数组相似但具有更大大小的数据结构)。 在此代码示例中可以看到for range的用法。 packagemainimport"fmt"funcmain(){data:=[5]int{1,2,3,4,5}//declares an array of intfori,v:=rangedata{fmt.Println("index: ",i,"value:...

for range value 在遍历中存在对容器元素的拷贝 遍历开始,已经确定了容器长度,中间添加的数据,不会遍历到 针对此测试如下: type Item struct { id int val [4096]byte } func BenchmarkLoopFor(b *testing.B) { var items [1024]Item for i := 0; i < b.N; i++ { ...
