Function getch in C program prompts a user to press a character. It doesn't show up on the screen. Its declaration is in 'conio.h' header file. The function is not a part of standard C library. C programming code for getch. Using getch in Dev C compiler. C standard library header files.; 2 minutes to read +1; In this article. Header files for the C standard library and extensions, by category. Headers by category. 11 Added in the C11 standard. 14 Added in the C14 standard. 17 Added in the C17 standard. 20 Added in the draft C. Jun 13, 2012 The C programming language defines a number of header files. Everyone has those header files. Graphics.h is something that YOU have, because YOU have turbo C and it comes with turbo C. Almost nobody else has it, because nobody else uses turbo C. The best advice I can give you is to not use turbo c. It's really, really old.
C++ graphics programming
Perhaps, the capacity of C++ to perform fast graphics display has contributed to the popularity of C++ in graphics and game programming. In this section, you will learn basic C++ graphics programming. This part is a good place to start learning graphics programming with C++. I also guide you to the process of installing graphics library and header files of freeglut package: Download here
Installing and configuring freeglut library and header files
Before you can write C++ code to display graphics on the screen, you need to install and configure graphics libraries and header files that C++ compiler can understand. freeglut package is a popular package that provides these libraries and header files. freeglut is an open source alternative to the GLUT toolkit (OpenGL Utility Toolkit) library that is a software interface to graphics harware. It can be used to produce colors images of moving, two and three-dimensional objects. After you download the freeglut package in zip format, unzip it in a proper place that you can find it. Then do the followings:
-Copy freeglut.dll file to Window System32 folder
-Copy all header files from freeglut/include/GL to include/GL folder of Dev-C++ compiler
-Copy libfreeglut.a file from freeglut/lib to lib folder of Dev-C++ compiler
-Open Dev-C++ window editor and create a new C++ project(Console Application)
-Open Project Option by pressing Alt+p
-In Linker box of Parameters, you need to add the following library files:
libopengl32.a
libfreeglut.a
You my find these two files in lib folder of Dev-C++ compiler
-Click Ok to save change
Now you are ready to start your first graphic program. Copy and paste the following code to your project:
#include <GL/freeglut.h>
using namespace std;
void showme(void);
void dis();
int main(int argc, char **argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DEPTH | GLUT_SINGLE | GLUT_RGBA);
glutInitWindowSize(400,400);
glOrtho(-1.2, 1.2, -1.2, 1.2, -1.2, 1.2);
glutCreateWindow('Teapot');
setup();
glutDisplayFunc(showme);
glutMainLoop();
return 0;
}
//--- showme
void showme(void)
{
glutWireTeapot(0.6);
glutSwapBuffers();
}
void setup()
{
glClearColor(0.2,0.5,0.2,0.2);
glClear(GL_COLOR_BUFFER_BIT);
}
You need to include the freeglut.h file to your program by writing #include <GL/freeglut.h>. The glutInit() command initializes GLUT and processes any command-line argument. It should be called before other commands. glutInitDisplayModecommand specifies the color mode (ARGB or index-color) or buffer mode (single or double -buffer) to use. The glutInitWindowSize command specifies the size, in pixel, of the working window. The glOrtho command specifies the coordinate system to draw the images. The glutCreateWindow creates a window with OpenGL context. The window is not yet displayed until the glutMainLoop command. The glClearColor command specifies clearing color. The glClear actually clears the window to a specified color. With the glutDisplayFunc command you can specify objects to display on the window. The glutSwapBuffers command waits until the previous an next buffer completely displayed.

Hi pals,
I am a Newbie in C++ Programming field. I plan to add graphics.h header class in
Dev -C++ Version 4.9.9.2 from Bloodshed which is come along with Borland Compiler.
I follow the Steps in URL : http://www.uniqueness-template.com/devcpp/#step2

But I Got Error in the Sample code which test the Working , Please Help me
to get away from this problem . I am waiting to hear from you.

Which Header File Is Used For Graphics In Dev C++
You can't. graphics.h is not compatible with Dev-C++
