std::map and the heap

[Dy]

Hi, I have the following code:

typedef std::map MyMapType;
MyMapType myMap;
myMap\["abc"\] = "def";

This works as expected. But I want my map to be on the heap, so I tried this:

MyMapType \*myNewMap = new MyMapType;
myNewMap\["abc"\] = "def"; //  error C2107: illegal index, indirection not allowed
\*myNewMap\["abc"\] = "def"; //  error C2107: illegal index, indirection not allowed

The two lines are commented with the compile time errors it generates. What have I missed?

A pair of braces:

(*myNewMap)["abc"] = "def";

compiles well. BTW, you also missed to properly format your code (have a look at typedef statement in the OP). :)
