You could use

function arrayandfile()
    array = fill(0, 10)  # where 10 is the total number of values in the file
    counter = 0          # number of values actually put in array so far
    for line in eachline("file.txt")
        line_values = parse.(Int, split(line))
        array[counter + 1 : counter + length(line_values)] .= line_values
        counter += length(line_values)
    end
    
    return array
end

I’m not sure why this does not fulfil your criteria…
