Julia : create an arrays in for loop

Question

l want to create an array having this structure

k[1]= 1

k[2]= 2

k[3]= 3

k[4]= 4

l tried it in this way but it's not working

n= 10

for i in 1:n
 k[i]= i
end

any suggestions ?

Answer 1

You havent initialized the array, so calling k[1] or k[2] or k[n] wont return an error

You should either:

n= 10
k = Array(Int64, n) #or Float64 or Any instead of Int64
for i in 1:n
    k[i]= i
end

or you could

n= 10
k = []
for i in 1:n
    push!(k,i)
end

I suggest the former, the other method would be more suited if you woulnt be able to determine the size of the array beforehand
