## CouponDaysAfterSet

 intcouponDaysAfterSet( int sett int mat Finance::Banking::YearlyFreq freq Finance::Banking::YearBasis basis` = yb_USA` )
This function computes the number of days from the settlement date to the next coupon date. The year basis is taken into account.

For a security, the settlement date is the date after issue when the security is traded to the buyer. The maturity date is the date at which the security expires.

### Example 1

```#include <stdio.h>

#include <codecogs/units/date/date.h>
#include <codecogs/units/date/dateymd.h>
#include <codecogs/finance/banking/coupondaysafterset.h>

int main(void)
{
int settDate=Units::Date::date(1998, 1, 25);
int maturityDate=Units::Date::date(1999, 11, 15);

int days=Finance::Banking::couponDaysAfterSet(settDate,
maturityDate,
Finance::Banking::yf_SemiAnnual,
Finance::Banking::yb_Act);
int y, m, d;

Units::Date::dateYMD(settDate, y, m, d);
printf("settlement=%i/%i/%i\n", y, m, d);

Units::Date::dateYMD(maturityDate, y, m, d);
printf("maturity=%i/%i/%i\n", y, m, d);

printf("days after settlement=%i\n", days);

return 0;
}```
Output:
```settlement=1998/1/25
maturity=1999/11/15
days after settlement=110```
