Networld,
Here's an easy question, for a usually non programmer. I wish to write
a simple C program to calculate the number of days between two dates.
Normally, I would use strptime
#include <time.h>
const long secondsperday = (24 * 60 * 60);
struct tm first, second;
strptime("10/1/1972", "%x", &first)
strptime("12/10/1999", "%x", &second)
printf("%d\n", (mktime(&second) - mktime(&first)) / secondsperday);
for example, but djgpp compiler does not have strptime. Can someone
please suggest an alternative? Exactly if possible.
Thanks!
