Thread: STL help

How come I can do like this:

Code:

#include <iostream>
#include <vector>
using namespace std;

int main()
{
	
	// Some constants
	const int nRows = 5;
	const int nCols = 11;

	//Typedefs to save our fingers and improve readability
	typedef vector<char> cArrayRow;
	typedef vector<cArrayRow> cArray;

	// Make an array:

	cArray myArray(nRows,cArrayRow(nCols));
}

but not like this:

Code:

#include <iostream>
#include <vector>
using namespace std;

int main()
{
         const int nRows = 5;
	const int nCols = 11;
	vector<vector<char>> test(nRows, vector<char>(nCols));
}

I dont know much about STL but why can I do the former but not the later since they seem to be quite the same to me, only one uses typedefs and the other doesnt.
Even this wont work:

Code:

vector<vector<char>> test;

Add a space between the >.

Code:

vector<vector<char> > ...
