a question on vector declaration

[Jee]

Hi,
I wonder what's wrong with the following,

std::vector<pair<int, int>> myVec;

The compiler always complains that "expect , instead of >>".

Thanks.

">>" is the right shift operator, you need to use:

std::vector<pair<int, int> > MyVec;


And std:air would make more sense since you are suing std::vector...

Same error after I change it to

std::vector<std:air<int, int>> myVec;

Any idea?

Read Sam's reply again. He already answered your question.

Read Sam's reply again, carefully.

std::vector<std:air<int,int> > myVec;

It is very simple.
You MUST have a space between th two '>' characters at the end of the
statement. Without the space, the compiler thinks it is a shift operator.

The statement You would should look like this :

std::vector<std:air<int, int> > my Vec ;

Note the Space between the two '>'
