how do i initialize a class' private member static map whose value is a struct?

Question

I have a class whose private member is a static map: ``` Class Devices { ... private: struct DevicePair { int nCtr; bool isToAdd; }; DevicePair m_DevPair; static map m_SYSdeviceMap; }; ``` Why can't I just do this in the cpp file? ``` map Devices::m_SYSdeviceMap; ``` How do I initialize this in the cpp file?

Accepted Answer

With this line:

```
map<string, Devices::DevicePair> Devices::m_SYSdeviceMap;
```

Also, as a good coding practice, remove the `using namespace std;` from your header, and qualify your use of map - `std::map`.
