Why is it not printing in the output.txt file thank you! and how can I also print the words in the output file. there must be a conflict between the while function before printing the input. or maybe there is something reading before the output then having conflict with another one, when I remove the while function (count words) it shows the product in the output.
CodePudding user response:
You read from fpr
until you reach EOF
, then try to read from it again.
You need to rewind
the file to the beginning for the second fgetc()
loop to produce anything.
