execute dll with parameters

Hello my Friends,
ive got a question about handling with dlls. ive a special dll from a customer which contains a algorithm and i want to test this algorithm with user specific values and collect the results. I am a hardcore beginner in c++ and sorry for that.
2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
string dllAbsolutePath =
LPCSTR result = dllAbsolutePath.c_str();
if(file.is_open() == false)
cout << "*.dll initiliazed failed" << endl << endl;
cout << endl << endl;
// dll loaded successfully
HMODULE hMod = LoadLibrary(dllAbsolutePath.c_str());
pFunc = GetProcAddress(hMod, "Algorithm_Function");
cout << pFunc << endl;
Right now i get only the Address of the Function but i want that this Function calculate some Values for me.
I hope that you can support me

You need to know the signature of the function you want to test in order to call it correctly.
Create a function pointer with the correct signature, assign pFunc to that function pointer. Then call the function via the new function pointer.
2 3 4 5 6
int (*somefunc) ( int arg1, int arg);
somefunc = ( int (*)( int, int)) pFunc; // cast function pointer
rslt = (*somefunc) (1,2);
Note the cast from the void pointer to the signature of the function.
