What is Dev-C++? Dev-C++, developed by Bloodshed Software, is a fully featured graphical IDE (Integrated Development Environment), which is able to create Windows or console-based C/C++ programs using the MinGW compiler system. MinGW (Minimalist GNU* for Windows) uses GCC (the GNU g++ compiler collection), which is essentially the same compiler system that is in Cygwin (the unix environment program for Windows) & most versions of Linux. There are, however, differences between Cygwin and MinGW; links to Differences between Cygwin và MinGW for more information. Click picture to enlarge.

Bloodshed!?
I"ll be the first khổng lồ say that the name Bloodshed won"t give you warm và fuzzies, but I think it"s best if the creator of Bloodshed explains: First I would like to say that I am not a satanist, that I hate violence/war & that I don"t lượt thích heavy metal / hard-rock music. I am french, but I vị know the meaning of the "Bloodshed" word, và I use this name because I think it sounds well. If you are offended by the name, I am very sorry but it would be a big mess khổng lồ change the name now. There"s also a reason why I keep the Bloodshed name. I don"t want people khổng lồ think Bloodshed is a company, because it isn"t. I"m just doing this khổng lồ help people. Here is a good remark on the Bloodshed name I received from JohnS: I assumed that this was a reference khổng lồ the time and effort it requires of you khổng lồ make these nice software programs, a la "Blood, Sweat và Tears". Peace và freedom, Colin Laplace Getting Dev-C++ The tác giả has released Dev-C++ as free software (under GPL) but also offers a CD for purchase which can contain all Bloodshed software (it"s customizable), including Dev-C++ with all updates/patches. links to Bloodshed Dev-C++ for a danh mục of Dev-C++ download sites. You should let the installer put Dev-C++ in the default directory of C:Dev-Cpp, as it will make it easier to lớn later install add-ons or upgrades. Using Dev-C++ This section is probably why you are here. All programming done for kinhdientamquoc.vnCI-2025 will require separate compilation projects (i.e. Class header file(s), class implementation file(s) and a main/application/client/driver file). This process is relatively easy as long as you know what Dev-C++ requires to vị this. In this page you will be given instructions using the Project menu choice. In another handout you will be given instructions on how to lớn manually compile, link and execute C++ files at the command prompt of a command window. See here. Step 1: Configure Dev-C++.

We need khổng lồ modify one of the mặc định settings to lớn allow you to use the debugger with your programs. Go to the "Tools" menu & select "Compiler Options". In the "Settings" tab, click on "Linker" in the left panel, & change "Generate debugging information" khổng lồ "Yes":
*
Click "OK". Step 2: Create a new project.
A "project" can be considered as a container that is used to lớn store all the elements that are required lớn compile a program. Go to the "File" menu & select "New", "Project...". Choose "Empty Project" và make sure "C++ project" is selected. Here you will also give your project a name. You can give your project any valid filename, but keep in mind that the name of your project will also be the name of your final executable. Once you have entered a name for your project, click "OK". Dev-C++ will now ask you where khổng lồ save your project. Step 3: Create/add source file(s). You can add empty source files one of two ways: Go khổng lồ the "File" menu & select "New Source File" (or just press CTRL+N) OR Go lớn the "Project" menu & select "New File". Lưu ý that Dev-C++ will not ask for a filename for any new source tệp tin until you attempt to: Compile Save the project Save the source file Exit Dev-C++ You can địa chỉ pre-existing source files one of two ways: Go khổng lồ the "Project" menu & select "Add khổng lồ Project" OR Right-click on the project name in the left-hand panel and select "Add khổng lồ Project".
EXAMPLE: Multiple source files
*
In this example, more than 3 files are required khổng lồ compile the program; The "driver.cpp" file references "Deque.h" (which requires "Deque.cpp") and "Deque.cpp" references "Queue.h" (which requires "Queue.cpp").
Step 4: Compile.

Once you have entered all of your source code, you are ready lớn compile. Go lớn the "Execute" menu and select "Compile" (or just press CTRL+F9). It is likely that you will get some kind of compiler or linker error the first time you attempt khổng lồ compile a project. Syntax errors will be displayed in the "Compiler" tab at the bottom of the screen. You can double-click on any error khổng lồ take you to lớn the place in the source code where it occurred. The "Linker" tab will flash if there are any linker errors. Linker errors are generally the result of syntax errors not allowing one of the files khổng lồ compile. Once your project successfully compiles, the "Compile Progress" dialog box will have a status of "Done". At this point, you may click "Close". Step 5: Execute. You can now run your program. Go to the "Execute" menu, choose "Run". Note: khổng lồ pass command-line parameters to lớn your program, go lớn the "Execute" menu, choose "Parameters" và type in any paramaters you wish to pass. Disappearing windows If you execute your program (with or without parameters), you may notice something peculiar; a console window will pop up, flash some text and disappear. The problem is that, if directly executed, console program windows close after the program exits. You can solve this problem one of two ways: Method 1 - Adding one library call: On the line before the main"s return enter: system("Pause"); Method 2 - Scaffolding: showroom the following code before any return statement in main() or any exit() or abort() statement (in any function): /* Scaffolding code for testing purposes */ cin.ignore(256, " "); cout "Press ENTER khổng lồ continue..." cin.get(); /* end Scaffolding */ This will give you a chance to lớn view any output before the program terminates và the window closes. Method 3 - Command-prompt: Alternatively, instead of using Dev-C++ khổng lồ invoke your program, you can just mở cửa an MS-DOS Prompt, go to the directory where your program was compiled (i.e. Where you saved the project) and enter the program name (along with any parameters). The command-prompt window will not close when the program terminates. For what it"s worth, I use the command-line method. Step 6: Debug. When things aren"t happening the way you planned, a source-level debugger can be a great tool in determining what really is going on. Dev-C++"s basic debugger functions are controlled via the "Debug" tab at the bottom of the screen; more advanced functions are available in the "Debug" menu. Using the debugger: The various features of the debugger are pretty obvious. Click the "Run to cursor" icon to run your program & pause at the current source code cursor location; Click "Next Step" khổng lồ step through the code; Click "Add Watch" lớn monitor variables. Setting breakpoints is as easy as clicking in the black space next khổng lồ the line in the source code. See the Dev-C++ help topic "Debugging Your Program" for more information. Dev-C++ User F.A.Q. Why vị I keep getting errors about "cout", "cin", and "endl" being undeclared? It has to bởi vì with namespaces. You need to add the following line after the includes of your implementation (.cpp) files: using namespace std; How vì chưng I use the C++ string class? Again, it probably has to bởi with namespaces. First of all, make sure you "#include " (not string.h). Next, make sure you địa chỉ "using namespace std;" after your includes. Example: #include #include using namespace std; int main() string s; s = "This is a test"; cout "PAUSE"); return 0; That"s it for now.
