Learn About Using Right Angle Brackets In This C++11 Feature For Windows Development

In the Clang-enhanced C++ compilers, two consecutive right angle brackets no longer generate an error, and these constructions are treated according to the C++11 standard.

C++03’s parser defines “>>” as the right shift operator or stream extraction operator in all cases. However, with nested template declarations, there is a tendency for the programmer to neglect to place a space between the two right angle brackets, thus causing a compiler syntax error.

C++11 improves the specification of the parser so that multiple right angle brackets will be interpreted as closing the template argument list where it is reasonable.

Right angle brackets example

#pragma hdrstop
#pragma argsused

#include <tchar.h>
#include <stdio.h>

#include <vector>
typedef std::vector<std::vector<int> > Table;  // OK
typedef std::vector<std::vector<bool>> Flags;  // OK

int _tmain(int argc, _TCHAR* argv[]) {

        return 0;
}
