Pointers are variables that store the memory address of another variable. Channels are used for communication between goroutines.

• Pointers allow direct access to memory, making it possible to modify values at a specific address.

• Channels are used to pass data between goroutines, allowing for synchronization and communication.

• Pointers can be used to pass large data structures to functions without copying the entire struct...read more

Goroutines are lightweight threads of execution in Go that allow concurrent programming.

• Goroutines are created using the 'go' keyword followed by a function call.

• They are executed concurrently with other goroutines and can communicate using channels.

• Switch statements can be used to control the flow of execution between multiple goroutines.

• Example: go func() { fmt.Println('Hello, world!') }()

• Example: select { case msg :...read more
