Hi...

C++ Syntax (Toggle Plain Text) 
  1. // read the whole file through one line at a time
  2.   while(getline(in, line))
  3.   {
  4.     // check does this line start with the tag string 'SER(FIT):' ?
  5.     // note: there must be no tabs/spaces at the start of the line
  6.     if(0 == line.find(tag))
  7.     {
  8.       // yes it does, then use a 
  9.       // stringstream object for extracting the values
  10.       stringstream sstrm(line);
  11.  
  12.  
  13.       if(sstrm >> dummy >> v1 >> v2 >> v3 >> v4 >> v5)
  14.       {
  15.         // extraction succeeded, now display the values
  16.         myfile 
  17.           << v1 
  18.           << "   "
  19.           << v2 
  20.           << "   "
  21.           << v3 
  22.           << "   "
  23.           << v4 
  24.           << "   "
  25.           << v5 
  26.           << '\n';}
  27.  
  28.       else
  29.       {
  30.         // display an error msg and break ...
  31.         myfile << "unexpected: unable to extract 5 values, stopping ...\n";
  32.         // break out of the while() loop
  33.         break;
  34.       }
  35.     }
  36.   }
you gave me this amazing code when i post a thread a bout log files..

but this code only works of file of this format:


C++ Syntax (Toggle Plain Text) 
  1. Input vector # 1:
  2. OUTPUT: 	1	0	1	0	0	
  3. **** Vdd = 1.8 **** Tclk = 0.1 ****
  4. SER(FIT): 	1.0e-002	1.5e-002	1.5e-002	1.3e-002	5.2e-003	
  5.  
  6.  
  7.  
  8. **********************************************************
  9. Input vector # 2:
  10. OUTPUT: 	0	0	1	0	0	
  11. **** Vdd = 1.8 **** Tclk = 0.1 ****

  21.  
  22. but if i want to change this code to print the numbers of a log file of this format :

Thanks for pointing out to the rest of us (what some of us already knew) why it is a totally bad idea just to give students code without those students showing some effort.

It seems that two months ago, you took your free cookie and then just left it at that, rather than sitting down and making sure you really understood it. The fact that you called it "amazing" tells us that you still have no clue.

So now you're back with "give me an idea on how could i change the code" and "i tried to do some changes on this code" asking for more free cookies.

> but i failed
Awww - what a shame.
How about posting YOUR attempt (something which you've never done as far as I can tell).

Are you going to leech off mitrmkar for the whole of your course?
