golang create empty slice of specified length

To create an empty slice of a specified length in Go (golang), you can follow these steps:

Step 1: Declare the slice variable. - Use the var keyword followed by the variable name. - Specify the type of the slice, followed by square brackets []. - For example, to declare an empty slice of integers, you can write: var mySlice []int.

Step 2: Allocate memory for the slice. - Use the make function to allocate memory for the slice. - Pass the type of the slice as the first argument, followed by the length of the slice. - For example, to create an empty slice of 5 integers, you can write: mySlice = make([]int, 5).

Step 3: Access and modify the elements of the slice. - You can access and modify the elements of the slice using the index notation. - For example, to assign a value of 10 to the first element of the slice, you can write: mySlice[0] = 10.

That's it! You have now created an empty slice of the specified length in Go. Remember to import the necessary packages if required.
