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.
