If s = "1 2 3 4 5", how could we obtain an Integer Array from this. I would like to return a 5 element Array{Int64,1} [1; 2; 3; 4; 5].

The string. split() method is used to split the string into various sub-strings. Then, those sub-strings are converted to an integer using the Integer. parseInt() method and store that value integer value to the Integer array.
1. The c_str() and strcpy() function in C++ C++ c_str() function along with C++ String strcpy() function can be used to convert a string to char array easily. The c_str() method represents the sequence of characters in an array of string followed by a null character ('\0').
str_split() Function This is an in-built PHP method that is used to convert a string into an array by breaking the string into smaller sub-strings of uniform length and storing them in an array.
As @isebarn used, split(s) is useful for splitting a string up into words (splitting by default at spaces):
julia> s = "1 2 3 4 5"
"1 2 3 4 5"
julia> split(s)
5-element Array{SubString{String},1}:
"1"
"2"
"3"
"4"
"5"
Now you can use an array comprehension:
[parse(Int, ss) for ss in split(s)]
Here, parse(Int, ss) parses a string ss into an integer.
Note also that this returns a one-dimensional vector, not a two-dimensional array. There is no reason to prefer a two-dimensional array here -- this is a naturally one-dimensional object.

If you are using version 0.5 or later, you can also do this:
int_s = parse.(split(s))
The trailing dot is the new compact broadcast notation. Possibly, this will be the preferred syntax in future versions.
