Question: How do I write code to get the current drive as well as set the current drive?
Answer: The function getdisk( ) returns the drive number of current drive. The drive number 0 indicates 'A' as the current drive, 1 as 'B' and so on. The Setdisk( ) function sets the current drive. This function takes one argument which is an integer indicating the drive to be set. Following program demonstrates use of both the functions.#include <dir.h> main( ) { int dno, maxdr ; dno = getdisk( ) ; printf ( "nThe current drive is: %cn", 65 + dno ) ; maxdr = setdisk ( 3 ) ; dno = getdisk( ) ; printf ( "nNow the current drive is: %cn", 65 + dno ) ; } |
