setdate() Method:
getdate() function is defined in dos.h header file. This function fills the date structure *dt with the system’s current date. Syntax
struct date dt; getdate(&dt);
Parameter: This function accepts a single parameter dt which is the object of structure date.
Return Value: This method does not return anything. It just gets the system date and sets it in the specified structure.
Note: The <dos.h> header file used in this tutorial works only on dos-based systems and will not work on Linux-based systems.
Program 1: Implementation of getdate() function
// C program to demonstrate getdate() method #include <dos.h> #include <stdio.h> int main()
{ struct date dt;
// This function is used to get
// system's current date
getdate(&dt);
printf ("System's current date\n");
printf ("%d/%d/%d",
dt.da_day,
dt.da_mon,
dt.da_year);
return 0;
