In the code example, we initialize an array with array literal. The values are given their index; the rest of the array elements are given 0 value. $ go run main.go [0 6 7 0 9] Infering array length Go can infer the array length when using array literals. For this, we use the ...
vararray= [5]int{1,2,3,4,5}// 这种方式,既初始化变量,又带了初始化值,数组长度已经定义好 Initializing an array using an array literal You can declare and initialize an array at the same time like this - // Declaring and initializing an array at the same time var a = [5]int{2, 4...
Below, we have given a small format of how we can initialize the array in go language. We have written the name of the array and defined the length as the 5, and we set the data type for the array as the int and array attributes we have defined as the 23,12 and 44. These attr...
