1. First you need to include the header file 2. You can now use the functions built into dos.h - delay - getdate - setdate - gettime - sound - nosound

#include "stdio.h" #include "dos.h" int main() { printf("Wait 10 seconds\n"); /* Sleep function prototype is available in dos.h */ sleep(10); return 0; }

First include dos.h header file then use their function. Before use function, you must have knowledge of dos functions and their charactistics

The header file dos.h was created to facilitate calls to System API and the OS, so that programmers could use system calls such as delay (int) or sleep (int) in their programs.

The header file dos.h was created to facilitate calls to System API and the OS, so that programmers could use system calls such as delay (int) or sleep (int) in their programs. But it was written at a time when DOS was the primary and Microsoft's only operating system! Unlike in the late 90s when it served as the shell on top of which early versions of Windows ran. But now, OSs like Windows Vista, 7, 8, 10 etc. are pure 32/64 bit systems and CMD is just an interaction utility that's provided to the user so that they can work on Command Line! Now you've got to realize that when Dev C++ was being developed, DOS was perishing and system calls could only be made on the OS on which the compiler is running, right? And that's when the header file windows.h was written to aid windows users and unix.h for unix users and so on. So, now there are two things you can do: You can copy the header file dos.h from an older compiler like TCC or your Turbo C++'s Lib to the Cygwin library that, I think Dev C++ uses. Although it may not work (compatibility/Security issues that modern compilers have); or Check the online documentation for windows.h and find the equivalent functions, and use them in your program, good luck read less

use #include preprocessor at top of your program to include this header file into ur program. Thus all functions of this header file will act as part of your program and then to use any of its function you can directly invoke that function instead of writing dos. command repeatedly.
