Put your Go programming knowledge to the test with this challenging quiz covering advanced concepts in Go. See how many correct answers you can get out of the 12 questions!
1. What is the primary purpose of Go's 'reflect' package?
To perform complex mathematical operations
To provide reflection to inspect the type of variables at runtime
To manage memory more efficiently
To handle all error reporting in Go
2. Which statement best describes a goroutine in Go?
A simpler form of a thread
A lightweight thread managed by the Go runtime
A process that runs independently of others
A function that necessarily consumes a lot of memory
3. How do buffered channels in Go operate?
By providing a buffer pool for memory optimization
By allowing only synchronous communication between goroutines
By allowing asynchronous communication with a specific capacity
By optimizing garbage collection frequency
4. What is the role of the 'select' statement in Go?
To run multiple goroutines concurrently
To handle multiple channel operations efficiently in a single goroutine
To defer function calls until the surrounding function returns
To initialize variables with default values
5. Which synchronization technique is used to wait for multiple goroutines to finish executing?
Mutex
Defer
WaitGroup
Select
6. What problem is the 'context' package in Go designed to solve?
Managing memory allocation
Handling efficient concurrency
Carrying deadlines, cancellation signals, and request-scoped values across API boundaries and goroutines
Improving type-safety in Go programs
7. What mechanism does Go use to manage memory automatically?
Manual memory management
Reference counting
Garbage collection
External memory manager
8. Which of the following is true about Go's deadlock detection?
Go cannot detect deadlocks
Go detects deadlocks only in the main function
The Go runtime can detect deadlocks and panic if it occurs
Deadlock detection is done during the compilation
9. Why is it important to close channels in Go?
To prevent memory leaks and indicate completion
To improve performance of the garbage collector
To automatically free all variables used by the channel
To increase the efficiency of the Go runtime scheduler
10. How does the Go runtime schedule goroutines?
Using system threads directly
Using a cooperative scheduler
Using a preemptive scheduler
By assigning each goroutine to a CPU core
11. Which technique can be used to inspect type information at runtime in Go?
Introspection
Reflection
Meta-programming
Dynamic typing
12. What is a practical use of Go's context package?
Optimizing code compilation
Synchronizing memory access between goroutines
Implementing timeouts and cancellation for goroutines
