How to allocate an array of channels

Question

How to create an array of channels?

For example: replace the following five lines with an array of channels, with a size of 5:

var c0 chan int = make(chan int); var c1 chan int = make(chan int); var c2 chan int = make(chan int); var c3 chan int = make(chan int); var c4 chan int = make(chan int); 

Answer 1

The statement var chans [5]chan int would allocate an array of size 5, but all the channels would be nil.

One way would be to use a slice literal:

var chans = []chan int {    make(chan int),    make(chan int),    make(chan int),    make(chan int),    make(chan int), } 

If you don't want to repeat yourself, you would have to iterate over it and initialize each element:

var chans [5]chan int for i := range chans {    chans[i] = make(chan int) }
