Hi,

I am trying to parse a txt file in C++. I usually use perl to parse thru text files but need to do it in c++.

Here is my text file.

NAME	BITMAPVBIREFE
MESSAGE	VirginBitMapiIrefE
VCCVALUE	3.000000
VIHSELECT	1
VIHVALUE	3.000000
WPSELECT	1
WPARGSELECT	0
WPVALUE	2.600000

I want to be able to parse the element related to the name and store it in a class. My class has setter functions to set the value of the element. I want to parse for instance VCCVALUE and retrieve 3.00000 and store that in a VccValue data member in my class. Can anyone tell me how to parse for the number. Thanks.

Read the file line by line, split it into tokens based on spaces, then convert the number token into a double from a string.

You may want to look at.

getline()
strtok()
strtod()

Hope that helps,
Chris

Another option would be to use a stringstream to parse the line once it's been read in using getline().
