Delete file from C

System invokes the DOS command interpreter file from inside an executing C
program to execute a DOS command to delete the file.

To be located and executed, the program must be in the current directory or
in the directories whose path is given.

---

>> So the following code delete the file whose location is specified.

#include<stdio.h>
#include<dos.h>
void main(void)
{
union REGS i,o;
char fname[67];
puts(“\nEnter file name: “);
gets(fname);
i.h.ah = 0×41;
i.x.dx = fname;
intdos(&i,&o); if(o.x.cflag == 0)
printf(“\n%s File successfully deleted”,fname);
else
printf(“\n%s File could not be deleted”,fname);
}
