How to Read specific data from file and do a calculation and display on the output

[chris_chua]

FYI: Below is the function use for the writing:

-OpenFile(use ASCII)
-sprintf
-WriteFile

Example: Output from the doc file

…EndTime: 09:34:48 program time: 0.567663 sec
…EndTime: 09:36:48 program time: 0.666666 sec

My objective is to read data 0.666666 (FYI: is last sentence of the file) to do some calculation. How can we read specific data(specific location) from file..

Any advice or help?
What is the function needed?

I would consider counting line feeds and checking for end-of file to isolate the last line, which then can be read using fscanf...

Have a look at getc...

character = fgetc ( stream );

if ( character == '\n' ) // new line

if ( character == EOF ) // end-of-file
