Searching for numbers from a a text file

[RSTR]

Is there a way to have searched through a text file like:

char line[256];
ifstream afile("c:\somefile.txt"
afile.getline(line, 255, '\n');

and assume that the first line of the text file was:
256.4223
That would mean that line[0] is = 2, [1] = 5 etc....

now lets say I have a float:
float x;
and I want x to equal the scanned number, 256.4223.
I can't say:
x = static_cast<float>(line);

this doesn't work. so what can I do to make x equal a number that was input from a text file?

atof(text) will return the value

that works. Also, I discovered the old C method:

sscanf(); I can't remember the syntax exactly right now, but it works great for parsing files =-)
