You include stdio.h when writing C code. If you are writing C++ code then you must include cstdio instead. Both headers implement the C standard input and output library but cstdio is compliant with C++.
Consider the following :
#include
int main()
{
printf("Hello world\n");
std::printf("Hello world\n"); // ERROR!
}
The error occurs because there's no guarantee the printf symbol resides in the std namespace. There's a small possibility it does reside there, but it is only guranteeed to exist in the global namespace. Thus the risk of error is high.
Now consider the following:
#include
int main()
{
using std::printf;
printf("Hello world\n");
std::printf("Hello world\n");
}
The cstdio header guarantees all symbols defined in stdio.h now appear in the std namespace (where all standard library symbols rightly belong). Although there's no guarantee those same symbols also reside in the global namespace, the using keyword can be used to inject those symbols into the global namespace. In this case the using keyword is unnecessary; the code will compile with or without it.
It's important to recognise the difference between C++ standard library headers (those with no extension) and the equivalent C headers (those with a .h extension). C headers guarantee all symbols are imported to the global namespace and possiblythe std namespace. C++ headers guarantee all symbols are imported to the std namespace and possibly the global namespace. In most cases, the C++ header simply modifies the equivalent C header to render it compliant with C++. This isn't always the case, but ultimately it is much easier to inject symbols to the global namespace (with using) than it is to inject to the std namespace. The C++ headers take care of all the messy stuff for you and are less problematic in the long run.
You write #include
If you look at these files, you will see macro definitions and function declarations. These are things that you need in order to be able to use the related libraries stdio.lib and/or conio.lib. Almost every C program will use stdio.h and/or stdlib.h, because those represent the standard run-time library. The conio.h file is specialized to make it easy to do special things with the console, such as do something on a keystroke without needing to press enter.
To find these files, look in the compiler's install directory, in the lib sub-directory. Just don't change anything in these directories, because they are a part of the compiler and run-time library. (To protect yourself, I suggest that you change your editor's default "save-on-exit" option to "ask", rather than "auto-save". This way, you won't accidentally change something that you shouldn't.)
conio.h is used for "Console Input/Output" function.
It is often used with text-based user interface programs. It has functions such as getch() which waits for a key to be pressed.
It also has color related functions. You can use them to change the color of text or background in a console application. It also has functions related to cursor movements, such as gotoxy().
conio.h is found in old MS-DOS compilers, such as Turbo C and is not widely supported.

You could, if you had conio.h in linux, but you don't have, that's why.
conio.h is a library function which is predefined in the header file and 'clrscr();','getch();' and many other functions come under this.

If you would use 'I' in the singular, then use 'you and I'. If you would use 'me', then use 'you and me'.
