How do I read several values from one text file in C?

The filename includes the variable name and the sensor number as: <variable_name>_<sensor_id>.txt

For example “BT_1.txt” is the file that contains the data collected by body temperature sensor 1.

BT files have the following format:

<time_stamp> <value> <units>

<time_stamp> <value> <units>

<time_stamp> <value> <units>

The text file looks like this:

0004   97.1   mW
0014   97.4   mW
0024   97.5   mW
0034   97.2   mW

How do I get the program to read the text file, and assign the proper values to the right varibles?

Later in the program I will need to manipulate these values.
