Difference between int main and void main and main Like any other function, main is also a function but with a special characteristic that the program execution always starts from the ‘main’. ‘int’ and ‘void’ are its return type. So, let’s discuss all of the three one by one. Void main – The ANSI standard says 'no' to the. When I compile my dos program and execute it, Dev-C minimizes and then restore in a second but nothing appears. When creating a console application, be sure to uncheck “Do not create a console” in Project Options (when working with source files only uncheck “Create for win32” in Compiler Options). Though this technique seems to work fine it hides a dangerous fault that can occur. This can be considered as a dis advantage of using c. This technique does not catch certain types of input. The following screenshots show 2 inputs that is accepted and the numerical part is printed. So, how can this erroneous inputs be handled? I am working on some more new usability features (controller and save state support) but I’ve not been feeling very motivated to work on this so its going slow. Plus, no one seems to be interested in N64 emulation so there’s that. Download from here.

How to Install Dev-C++ and the GLUT Libraries
for Compiling OpenGL Programs with ANSI C

(version of July 16, 2009)

These notes explain how to compile programs written in ANSI C with OpenGL and GLUT using the Dev-C++ compiler.

Bloodshed Dev-C++ is a free C++ compiler and development environment for Windows operating systems. Like most C++ compilers, it also can be used to compile ANSI C. By installing the GLUT header and library files, it can be used to write programs that use OpenGL. This is needed to run programs for Edward Angel's textbook, Interactive Computer Graphics 5^th edition and possibly other computer graphics texts.

These notes do not explain how to compile OpenGL with C++ . The 6^th edition of Angel's book uses C++ which will not work with these notes.

These instructions have been tested on a small variety of Windows 2000 and Windows XP systems. These systems come with the files needed for OpenGL, but not the files needed for GLUT.

Dev-C++ does not work well with Microsoft's Vista. The problem, and a possible fix, is discussed here: http://aresio.blogspot.com/2007/06/vista-and-dev-cpp.html but I have not tested this information.

I. Download Dev-C++ from http://www.bloodshed.net/dev/devcpp.html and install it.

Details:

Get Dev-C++ 5.0 beta 9.2 (4.9.9.2) (9.0 MB) with Mingw/GCC 3.4.2 Although this is a 'beta' version, it works perfectly fine. Click on SourceForge to go to a list of download sites and pick one. The file will be something like devcpp4.9.9.2_setup.exe. Save this file in a place like C:Temp.

When the download is complete, click on the 'open' button to start the installation process. (Or go to C:Temp andDouble click on devcpp4.9.9.2_setup.exe). You will see a few screens that ask you to pick a language (English) and to agree to the license terms. Choose a 'typical' installation.

Accept the suggested destination for the installation:

Many subdirectories and files are extracted to the destintion:

Answer 'yes' when it asks if you wish to install Dev-cpp for all users. Note: if the installation fails, re-install and try 'no' for this.

A screen says the installation is complete:

Keep the check mark in the box. Click on 'Finish'. A first-time configuration screen appears:

Pick 'English' and 'New Look'. In the next several screens, hit 'Yes' for its suggestions.

Eventually you are done. Click 'OK'.

II. DEV-C++ starts up. Try out the installation with a simple C program.

Void Main Not Working Dev C++ 2017

Details:

The program starts up automatically.

Click File/New/Project. Pick a name for the project (such as 'myProject'). Click 'C Project'. Click on 'Empty Project'. Click 'OK'.

In 'Create New Project', click 'save' (later on you will probably want to create separate subdirectories for your various projects.).

Click 'File/New/Source File' and in 'Add source file to current project' click 'Yes'. You now get a screen where you can edit the source file.

Type in a simple C program, as below. Now click 'File/Save As' and save the file as 'hello.c' (or other name.) Important: be sure that the file extension is .c. With any other extension (such as the suggested .cpp) you will have problems compiling.

Now click 'Execute/Compile and Run'

The program will (hopefully) compile, run, and write its output to a DOS window. If you have the system('pause') statement in your program, the output will stay in the window until you hit a key. Another way to run the program (after it has been compiled) is to start a DOS window outside of the Dev-Cpp system, then navigate to the subdirectory that holds your project, and type hello.exe.

At this point, the compiler and development environment has been installed. You should find Dev-C++ listed under 'Programs' on the 'Start' menu and will now be able to write, compile, and run C (and C++) programs. You will have include files, libraries, and dll's for OpenGL (and all other standard packages) but not GLUT. GLUT manages the windows and other user interface components needed for OpenGL programming, and needs to be separately installed.

If you do not need GLUT , you can quit now.

III. Download and install GLUT

Void Main Not Working Dev C++ Version

To run OpenGL with GLUT (which is what the programs in Angel's book use), you need to get three files and place each file in its proper directory. All the files you need (and more) are contained in one zip file.

Details:

Download GLUT files from http://chortle.ccsu.edu/Bloodshed/glutming.zip Download the file glutming.zip Save the zip file in some convenient location (perhaps C:temp).

Double click on glutming.zip (or otherwise unzip it). You will see the files that are in the zip archive. (Your un-zipping program will probably be diferent than the one shown here, but should work about the same.)

Click on 'Extract' to extract all the subdirectories and files. Pick some convenient directory to extract them to (perhaps C:tempglutming). You only need three files, but extract all of them anyway.

Only three of the files in the various subdirectories are needed. Each of the three files should be put in a subdirectory with other files of its type. Use Explorer to move the files to where they are needed.

Note: If you only see some of these files listed in Explorer, click on 'View/Options/View' and then select the radio button 'Show all Files'.

glut.h -- copy this file to C:Dev-CppincludeGL

Copy from your 'unzipped' subdirectories (wherever they are):

To here:

libglut32.a -- copy this file from your unzipped directories to C:Dev-Cpplib

There may be a newer version of this file there, already. Replace that version with the one you unzipped (if you keep the newer version your programs will not link correctly.)

Copy from your 'unzipped' subdirectories:

To here:

glut32.dll -- move this file to C:WINNTSystem32, or similar location.

The location for this file depends on your operating system. The directory where it goes is the directory that holds the dynamic load libraries (*.dll). An easy way to find where it should go is to look for glu32.dll (use 'Search' from the start menu).

The directory to use should also have the files glu32.dll and opengl32.dll. These should have come with your operating system.

IV. Test Dev-cpp with GLUT

The essential step in compiling and running a C program that contains OpenGL and GLUT functions is to tell the linker where the libraries are. This is done by clicking Project/Project Options/Parameters/Add Library or Options and then navigating to the libraries you need to include: libopengl32.a, libglu32.a, and libglut32.a. The libraries should be added in that order.

Details:

a. Create a subdirectory for a project. Do this first, before you start Dev-Cpp. Create a new subdirectory with 'Explorer' by clicking 'File/New/Folder'.

For example, create a folder C:GLproject.

b. Start Dev-cpp:
