How can buffer overflow errors be avoided in a program?

Buffer overflow in Go is usually related to improper management of slices or arrays. To avoid buffer overflow errors:

• Use built-in slices that dynamically manage length and capacity.
• Check indices before accessing elements to prevent going out of bounds of a slice or array.
• Use functions from the bytes.Buffer or bufio packages, which safely manage buffers.
• When reading data from external sources, limit the buffer size.

Example of safe appending to a slice:

var data []byte
newData := []byte{1, 2, 3}
data = append(data, newData...)

Thus, Go helps prevent buffer overflow through built-in mechanisms and strict boundary checks.
