function printsum(a)
    # summary generates a summary of an object
    println(summary(a), ": ", repr(a))
end

# arrays can be initialised directly:
a1 = [1,2,3]
printsum(a1)
#> 3-element Array{Int64,1}: [1, 2, 3]

# or initialised empty:
a2 = []
printsum(a2)
#> 0-element Array{Any,1}: Any[]

# since this array has no type, functions like push! (see below) don't work
# instead arrays can be initialised with a type:
a3 = Int64[]
printsum(a3)
#> 0-element Array{Int64,1}: Int64[]

# ranges are different from arrays:
a4 = 1:20
printsum(a4)
#> 20-element UnitRange{Int64}: 1:20

# however they can be used to create arrays thus:
a4 = collect(1:20)
printsum(a4)
#> 20-element .........完整代码请登录后点击上方下载按钮下载查看
