func main() { c := { Name: "cookie", Value: "\"hello\"", } fmt.Println(c) } 1. Why too much work being done while printing , shouldn't this be done only once? 2.

Attached two files main.c and main.go, both try to compute fib(40), 20 times on `x` no.of threads/goroutines. fib(40) is recursive. *Prerequisites for C:* 1. libuv (https://github.com/libuv/libuv) *Compile*: - *C :* - *Unoptimized:* * gcc main.c -lpthread -luv * -

[go-nuts] Why isn't golang input and output is buffered?

I have seen that python input and output is buffered, but golang's input and output is not buffered. For those types of problems where i need to take large amounts of input, It's taking long time to just take input than to do processing. When we have advantages with buffered input and output,
