Question

I have a function declared as:

int myFunction(const float** ppArr, const int n, const int m);

and when I call it like so:

float** ppArr = new float*[5];
// Some initialization of ppArr

int result = myFunction(ppArr, 5, 128);  <<<< Error

and the error is (VS 2008 Express):

error C2664: 'Test_myFunction.cpp' : cannot convert parameter 1 from 'float **' to 'const float **'

WTF? I’m casting a float** to const float**. What could possibly go wrong with that ? :/

Edit: Thank you for incredibly fast responses!!! 🙂

Please read “Why am I getting an error converting a Foo** → Foo const**?” at C++ FAQ.
