Arrays are a built-in data type in Golang. An array can store a fixed number of elements of the same type.
The code below shows how to declare an array that can store up to elements with the string type specification.
newArray := [4]string{"a", "b", "c", "d"}
We can perform the following steps to delete an element from an array:
The code below deletes the value "c" from an array in Golang:
package mainimport ("fmt")func main(){// initialize an arrayoriginalArray := [4]string{"a", "b", "c", "d"}fmt.Println("The original array is:", originalArray)// initialize the index of the element to deletei := 2// check if the index is within array boundsif i < 0 || i >= len(originalArray) {fmt.Println("The given index is out of bounds.")} else {// delete an element from the arraynewLength := 0for index := range originalArray {if i != index {originalArray[newLength] = originalArray[index]newLength++}}// reslice the array to remove extra indexnewArray := originalArray[:newLength]fmt.Println("The new array is:", newArray)}}
In the code above:
fmt package for printing.string called originalArray. At the time of declaration, originalArray contains four values.if statement in line 17 ensures that the index of the element to delete is within the valid range. In the case of originalArray, the valid range of indices is between 0-3.newLength, whose value will be incremented whenever we copy back a value into the array.for loop to iterate over each value in the array.newLength, and the value of newLength is incremented.originalArray to newArray up until the index pointed to by newLength.
