How do I convert a string (with a dollar sign) to a double in C++?

Question

I'm not quite sure how to do this, but I want to convert "$63.50" in a string to "63.50" in a double. How would I go about doing this in C++? Thanks.

Answer 1

given that your variable is named Amt

Amt.erase(1,1);

Answer 2

first, strip the dollar sign, then convert it to a float.

Personally, I'd say:

double var = atof ( mystring.c_str () + 1 );

That's rather C-ish, but it will work.
