How to insert spaces in string?

I am trying to insert spaces in string

for example:

string = "hellohowarejames"

i woud like to insert a space for every 4 letters

so it will look like

"hell ohow arej ames"

Something like this untested, bug filled code?

Code:

string AddSpaces(string Input)
{
	int length = Input.size();
	string output = string.empty;

	//for each block of 4 characters
	for(int i =0 ; i< length; i=i+4)
	{
		//copy 4 characters and a space to the output
		output += Input.substr(i, 4) + " ";

	}
	return output;
}

He he, Spot the C# programmer!
In C++ we just declare it and leave the default constructor to make it empty.

Code:

output := '';

I am coding everyday in PL/SQL, C#, VB.NET and ASP.NET at the moment, with some JavaScript thrown in to be annoying.

I keep mixing syntax up and adding 'THEN' after loops/IFs.

Worse is when I code in PL/SQL

Code:

IF (someVar <> NULL) THEN
