Fix

The error occurs because you are trying to take the address of a value that is not addressable, such as a literal, a function return value, or a map index result. You must assign the value to a variable first, then take the address of that variable.

// Incorrect: cannot take address of literal or function result
// ptr := &MyStruct{Field: 10}
// ptr := &getStruct()

// Correct: assign to a variable first
val := MyStruct{Field: 10}
ptr := &val

// Or if calling a function
val = getStruct()
ptr = &val

In Go, you can only take the address of something that lives in a specific memory location, like a variable. You cannot take the address of temporary values like numbers or results from functions because they don't have a fixed location. Think of it like trying to write a house address for a person who is currently walking down the street; you need them to stop at a specific house (variable) first.
