Hi all,
I have this code here and I like to save all the messages into 1 text file name contimer.txt. I've tried to do
FILE *output
fopen(output,"comtimer.txt", "ww");right before the function Timer 1 and change every "printf" function into fprint_s(f, "Message", variables) but it does not help. Could I have some pointers? Thank you.
This is my full code:

double t1;
