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

Initialize array

The following demonstrates array initialization:

Var balance = [5] float32 {1000.0, 2.0,3.4,7.0,50.0}

We can also quickly initialize the array while declaring it literally:

Balance: = [5] float32 {1000.0, 2.0,3.4,7.0,50.0}

If the length of the array is uncertain, you can use. Instead of the length of the array, the compiler deduces the length of the array based on the number of elements:

Var balance = [...] float32 {1000.0, 2.0,3.4,7.0,50.0} or balance: = [...] float32 {1000.0, 2.0,3.4,7.0,50.0}

If the length of the array is set, we can also initialize the element by specifying the subscript:

/ / initialize the elements with indexes 1 and 3 balance: = [5] float32 {1VOR 2.0pm 3JR 7.0}

The number of elements in the initialization array {} cannot be greater than the number in [].

If you ignore the numbers in [] and do not set the size of the array, the Go language sets the size of the array based on the number of elements:

Balance [4] = 50.0

The above example reads the fifth element. Array elements can be read (or modified) by index (position), which starts at 0, the first element index is 0, the second index is 1, and so on.
