In this article, the editor introduces in detail "how Go accesses array elements". The content is detailed, the steps are clear, and the details are handled properly. I hope this article "Go how to access array elements" can help you solve your doubts.

Access array elements

Array elements can be read by index (position). The format is the array name followed by parentheses, and the value of the index is in the brackets. For example:

Var salary float32 = balance [9]

The above example reads the value of the 10th element of the array balance.

The following shows an example of a complete operation of an array (declaration, assignment, access):

Example 1

Package main

Import "fmt"

Func main () {

Var n [10] int / * n is an array of length 10 * /

Var i,j int

/ * initialize elements for array n * /

For I = 0; I < 10; iTunes + {

N [I] = I + 100 / * set the element to I + 100 * /

}

/ * output the value of each array element * /

For j = 0; j < 10; jacks + {

Fmt.Printf ("Element [% d] =% d\ n", j, n [j])

}

}

The execution result of the above example is as follows:

Element [0] = 100Element [1] = 101Element [2] = 102Element [3] = 103Element [4] = 104Element [5] = 105Element [6] = 106Element [7] = 107Element [8] = 108Element [9] = 109. at this point, the article "how to access array elements by Go" has been introduced.
