Hi There,
I have a c code that produces a list of numbers,
What is the easiest way I can output these to a file that I can see in excel (so i can make a graph).
Currently the code is in a loop that produces 12,000 results based on the previous result.
It currently uses the printf function to prodcue the answers on a screen.

Make it a tab or comma separated file, you can import that to excel.
Well if you have
1,2,3
Then you can just do something like
myprog.exe > myresults.csv
Double-clicking on that file in explorer should run excel automatically and import the data.
If you've got any other kind of separator, then just run excel and do "import file", where you have the chance to specify all sorts of things like field widths, formats, separators etc.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
really daft so i have my printf (Input)
Loop
printf(Output)
How do i print these to a file?
Ive only ever outputed data as printf()

You need to open a new file for writing using fopen, then you write to it using fprintf (almost identical syntax to printf) and close it again with fclose. Or you can do what Salem says and redirect the output directly to a file.
