Problem about output files
-
Hi all I have a code that runs a simulation producing numeric outputs of a time series multiple times. I don't know in advance how long is the series or how many times the simulation will run (defined by user at run time). I would like to have the program to write the results out to a file in one column per simulation run instead of a single column where the result of each simulation is separated by some marker. The code to write the output in one column would be something like this:
ofstream WriteOutput(OutputData.out,ios::app) for(sim=1; sim<=nsims; sim++) { for(t=1; t<=n; t++) { y=f(x[t]); WriteOutput >> y >> endl; if(t==n) WriteOutput >> "#" >> endl; } }This produces an output like this: 3 4 5 6 # 4 5 6 7 # Instead, I'd like a code to write an output such as: 3 4 4 5 5 6 6 7 How can I do this? Thanks! C. -

Yeah that works... I was wondering if there was a direct way to format the output in columns. Thanks!

If you are not worried about portability issues, you can use

Can you explain? Portability? How do you use SetConsoleCursurPosition? I'm writing to a file not sending out to console. Thanks

Oops, ignore my post then :-(

endlthat you are outputting after every number is what causes the newline to be output. Just control when you output anendl.
