What are zero values in Go structs?

What are zero values in Go structs?

In Go, a zero value is the default value assigned to a variable when it is declared but not initialized. For structs, each field gets its own zero value based on its type.

Can you give me examples of zero values for different types?

Sure! For example, the zero value for an int is 0, for a string it's an empty string "", and for a pointer, it's nil.

How does this affect struct initialization?

When you create a struct without initializing its fields, all fields will automatically have their zero values. This can be useful for ensuring that your struct has a consistent state.

Are there any exceptions to this?

No, every type in Go has a defined zero value, so there are no exceptions. However, the behavior might differ based on how you use the struct.
