What is the header file for delay?
delay() function is used to hold the program’s execution for given number of milliseconds, it is declared in dos. h header file.
What is the use of process H header file in C++?
h is a C header file which contains function declarations and macros used in working with threads and processes. Most C compilers that target DOS, Windows 3.1x, Win32, OS/2, Novell NetWare or DOS extenders supply this header and the library functions in their C library.
What is the use of conio h in C?
h is a C header file used mostly by MS-DOS compilers to provide console input/output. It is not part of the C standard library or ISO C, nor is it defined by POSIX. This header declares several useful library functions for performing “istream input and output” from a program.
What is sleep function C?
The function sleep gives a simple way to make the program wait for a short interval. If your program doesn’t use signals (except to terminate), then you can expect sleep to wait reliably throughout the specified interval.
Why void main is used in C?
The void main() indicates that the main() function will not return any value, but the int main() indicates that the main() can return integer type data. When our program is simple, and it is not going to terminate before reaching the last line of the code, or the code is error free, then we can use the void main().
Why do we use header files?
Header files are used in C++ so that you don’t have to write the code for every single thing. It helps to reduce the complexity and number of lines of code. It also gives you the benefit of reusing the functions that are declared in header files to different .
What is STDIO and CONIO?
STDIO means Standard Input Output. It has some pre-defined functions like int printf(), scanf() etc. CONIO stands for Console Input Output which has some functions like clrscr(), getch() etc. conio.
What is the full form of Getch?
The getch() function basically stands for ‘get character’. As one would understand from the title, getch() gets a character from the user. The getch() function is usually used to hold the output screen until the user presses on the keyboard, i.e. the case of pressing any key to continue.
What is System CLS in C?

What is Fflush in C?
CProgrammingServer Side Programming. The function fflush(stdin) is used to flush the output buffer of the stream. It returns zero, if successful otherwise, returns EOF and feof error indicator is set.
Why do we need H files?
The primary purpose of a header file is to propagate declarations to code files. Header files allow us to put declarations in one location and then import them wherever we need them. This can save a lot of typing in multi-file programs.
Why we use Stdio h in C?
It is used to print the strings, integer, character etc on the output screen. It reads the character, string, integer etc from the keyboard. It reads the character from the file. It writes the character to the file.
What is the use of DOS h in C?
Dos.h. Dos.h in C: Dos.h header file of C language contains functions for handling interrupts, producing sound, date and time functions etc. It is Borland specific and works in Turbo C compiler.
What is the use of Dosdos in C?
dos.h in c: dos.h header file of c language contains functions for handling interrupts, producing sound, date and time functions etc. It is borderland specific and works in turbo c compiler.
What is the use of the header DOS file in C?
Dos.h is one among the header files . It contains functions for handling interrupts, producing sound, date and time functions etc. It is a Borland specific and works in turbo c compiler.
Is there any equivalent header for DOS h in Linux?
I know that the dos.h header file is not valid in Linux. Is there any other equivalent header for dos.h in Linux? Show activity on this post. Linux is a Posix/Unix like system, so you should learn the system calls and facilities that you can use. Read the advanced unix programming book (or some equivalent; AUP is considered a very good book).
