How do I get the difference between two dates in C++?
Total = Y* 365 + M*30 + D ,then find the difference between 2 totals of the corresponding dates. While multiplying 30 with M value ,you have to give the number of days in that month. You can do it with #define value or if loop. Similarly you can do for leap year too by multiplying 366 with Y .
