Compiling a program containing this code:

using namespace std;
...
string c;
f = atof(c.c_str);

I get the following error in MSVC++

error C2664: 'atof' cannot convert parameter 1 from 'const char *(void) const' to 'const char *'

Anyone help?

atof() takes a 'const char *' as the parameter, what is c_str set to?
maybe casting it to char* will work

f = atof((const char *)c.c_str);

You´re trying to convert a function (method) pointer to a char*. Try the next:

using namespace std;
....
string c;
f = atof(c.c_str());

Thanks,

I remember falling for that one before.

That's what happens when I spend too much time coding in Delphi.
