m := make([]int, 0, 10) // allocate memory for a slice
for i := 0; i < 10; i++ {
m = append(m, i) // safely append elements
}
fmt.Println(m) // output memory contents safely
}Another crucial element is Go’s handling of pointers. Go enforces strong typing, reducing the chances of accidental memory corruption. The following demonstrates how Go validates pointer usage:
package main
import "fmt"
func main() {
var ptr *int // declare a pointer
value := 42
ptr = &value // safely assign address of value
fmt.Println(*ptr) // dereference safely to output value
}In these examples, Go’s memory safety is evident through its robust features, ensuring that memory management remains intuitive and secure for developers, particularly beneficial for beginners in coding.
