Question

I’m coding a network game in C. I ‘ve written scores in a file. I also wanted to add the date of the day.
Here is the file’s structure : Date Name Score
and the code :

ScoreFile = fopen("scores.txt", "a");
fprintf(ScoreFile, "%s %d\n", Name, Score);

I’ve tried system(“date”) but it’s printed on stdout. I think that I can’t add the Date with fprintf.

Do you know a solution that permits to add Date in a file ? (maybe something from time.h ?)

thanks a lot !!

Consider using strftime to convert the time structure to string.

Example (from link above):

#include <time.h>
// ...

char s[30];
size_t i;
struct tm tim;
time_t now;
now = time(NULL);
tim = *(localtime(&now));
i = strftime(s,30,"%b %d, %Y; %H:%M:%S\n",&tim);

puts Jul 9, 2011; 17:55:55\n in s
