Example
The point is that RWDate allows you to quickly and easily manipulate the calendar dates you're
most likely to use. Here is an example that demonstrates the virtuosity of the class.
Let's print out the date when ENIAC first started, 14 February 1945, then calculate and print the
date of the previous Sunday, using the global locale:
#include
#include
int main(){
// ENIAC start date
RWDate d(14, "February", 1945);
// Today
RWDate today;
cout << d.asString("%A, %B %d 19%y")
<< " was the day the ENIAC computer was" << endl
<< "first turned on. "
<< today - d << " days have gone by since then. " << endl;
return 0;
}
Program Output:
Wednesday February 14, 1945 was the day the ENIAC computer was
first turned on. 18636 days have gone by since then.
In this calculation, notice that the number of days that have passed depends on when you run the
program.
