golang cannot address object

Golang is a simple and efficient programming language that is especially good at concurrent programming. However, you may encounter some difficulties and problems when programming with golang. One of the common problems is "golang cannot address object".

In golang, if an object is allocated on the stack, the address of the object cannot be obtained directly. This is because objects allocated on the stack are destroyed when the function returns, so there is no guarantee that the obtained address is still valid. If you try to get the address of an object allocated on the stack, you will get a "golang cannot address object" error.

The solution to this problem is to allocate the object on the heap instead of the stack. You can use golang's "new" function to allocate heap memory for an object and return a pointer to the object. According to golang's specification, objects allocated using the "new" function are always allocated on the heap, so their address can be obtained safely.

The following is a simple example of how to use the "new" function to solve the problem of "golang cannot address the object":

type Person struct {
    name string
    age  int
}

func main() {
    p := new(Person)
    p.name = "Tom"
    p.age = 25
    fmt.Printf("Person: %v, address: %v
", *p, p)
}

In this example, we define a "Person ” structure and allocates a new “Person” object using the “new” function. Note that we do not use "&" to get the address of the object, but directly pass "p" as a parameter to the "Printf" function. This is because objects allocated using the "new" function are always allocated on the heap and their address can be safely obtained.

Finally, we print the "Person" object and its address to the console. As you can see, we successfully obtained the address of the object, and the program did not cause the "golang cannot address the object" error.

To summarize, the problem of golang being unable to address objects is caused by the fact that objects allocated on the stack will be destroyed when the function returns. To solve this problem, we can use the "new" function to allocate heap memory for an object and return a pointer to the object. This can avoid the error "golang cannot address the object" and ensure the normal operation of the program.
