How To Run Multiple Cpp Files Dev C++
The most basic multi-module monster project in C programming has two source code files. Each file is separate — written, saved, and compiled individually — but eventually brought together as one unit by the linker. The linker, which is part of the build process in Code::Blocks, is what creates a single program from several different modules.

What’s a module?
Dec 11, 2017 How to Compile and Run C/C program on Linux. Create a file called demo.c using a text editor such as vi, emacs or joe. How do I compile a program with multiple source files? The syntax is as follows if the source code is in several files (such as light.c, sky.c, fireworks.c). What is the procedure to run.cpp program in linux distro. Used in C programming language. Although a C compiler like Dev-C allows you to compile a C program that includes some features of C, in this course we will concentrate on C programming language. A program written in pure C language may be compiled and run using other C compilers, like Turbo C etc. Dev-C interface. Oct 07, 2019 Save this file as test.cpp. Run your code using Code Runner. Use the shortcut Ctrl+Alt+N; Or press F1 and then select/type Run Code; Or right-click the Text Editor and then click Run Code in the editor context menu; The code will run and the output will be shown in the Output Window. Open the output window with `Ctrl+ shortcut.
A module is a source code file and its compiled object file. Together, the source code and object files are a module. Then the various object files are linked to build a program. The entire operation starts with separate source code files.
THE MAIN.C SOURCE CODE FILE
Exercise 1: Fire up a new project in Code::Blocks named ex2401. Create the project as you normally would: Type the source code from The main.c Source Code File into the editor as the contents of the main.c file. Save the file.
Don’t build yet! After all, the code references the second() function, which doesn’t seem to exist anywhere. It’s prototyped, as is required for any function that’s used in your code, but the second() function is found in another module. To create that module in Code::Blocks, follow these steps:
Save the current project, ex2401.
Why is little snitch b ocking web. Choose File→New→Empty File.
Click the Yes button when you’re prompted to add the file to the active project.
The Save File dialog box appears.
Type alpha.c as the filename and then click the Save button.
The new file is listed on the left side of the Code::Blocks window, beneath the Sources heading where the main.c file is listed. A new tab appears in the editor window, with the alpha.c file ready for editing.
Click the alpha.c tab to begin editing that file.
Type the source code from The alpha.c Source Code File into the alpha.c file in Code::Blocks.
Save the ex2401 project.
Build and run.
THE ALPHA.C SOURCE CODE FILE
Here’s the output you should see in the test window on your computer:

The two source code files aren’t “glued together” by the compiler; each source code file is compiled individually. A separate object code file is created for each one: main.o and alpha.o. It’s these two object code files that are then linked together, combined with the C standard library, to form the final program.
The main module for a multi-module C program is traditionally named main.c. That’s probably why Code::Blocks names the first (and, often, only) project source code file main.c.
Only source code files contained within the same project — found beneath the Sources branch — are linked together.
To compile and link source code files in a terminal window, use the following command:
This command compiles the source code files main.c and alpha.c, links together their object files, and then creates as output (-o) the program file ex2401.
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) and most versions of Linux. There are, however, differences between Cygwin and MinGW; link to Differences between Cygwin and MinGW for more information.
Bloodshed!?
I'll be the first to say that the name Bloodshed won't give you warm and fuzzies, but I think it's best if the creator of Bloodshed explains:
There's also a reason why I keep the Bloodshed name. I don't want people to think Bloodshed is a company, because it isn't. I'm just doing this to help people.
Here is a good remark on the Bloodshed name I received from JohnS:
I assumed that this was a reference to the time and effort it requires of you to make these nice software programs, a la 'Blood, Sweat and Tears'.
Peace and freedom,
Colin Laplace
Getting Dev-C++
The author 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.

You should let the installer put Dev-C++ in the default directory of C:Dev-Cpp, as it will make it easier to later install add-ons or upgrades.
Using Dev-C++
This section is probably why you are here.
All programming done for CSCI-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 do 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 manually compile, link and execute C++ files at the command prompt of a command window. See here.
Step 1: Configure Dev-C++.
We need to modify one of the default settings to allow you to use the debugger with your programs.
- Go to the 'Tools' menu and select 'Compiler Options'.
- In the 'Settings' tab, click on 'Linker' in the left panel, and change 'Generate debugging information' to 'Yes':
- Click 'OK'.
Step 2: Create a new project.
A 'project' can be considered as a container that is used to store all the elements that are required to compile a program.
- Go to the 'File' menu and select 'New', 'Project..'.
- Choose 'Empty Project' and 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 to save your project.
Step 3: Create/add source file(s).
You can add empty source files one of two ways:
- Go to the 'File' menu and select 'New Source File' (or just press CTRL+N) OR
- Go to the 'Project' menu and select 'New File'.
Note that Dev-C++ will not ask for a filename for any new source file until you attempt to:- Compile
- Save the project
- Save the source file
- Exit Dev-C++
- Go to the 'Project' menu and select 'Add to Project' OR
- Right-click on the project name in the left-hand panel and select 'Add to Project'.
EXAMPLE: Multiple source files In this example, more than 3 files are required to 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 to compile.
- Go to 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 to 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 to take you to 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 to compile.
Step 5: Execute.
You can now run your program.
- Go to the 'Execute' menu, choose 'Run'.

Note: to pass command-line parameters to your program, go to the 'Execute' menu, choose 'Parameters' and 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:
Add the following code before any return statement in main() or any exit() or abort() statement (in any function):/* Scaffolding code for testing purposes */
This will give you a chance to view any output before the program terminates and the window closes.
cin.ignore(256, 'n');
cout << 'Press ENTER to continue..'<< endl;
cin.get();
/* End Scaffolding */ - Method 3 - Command-prompt:
Alternatively, instead of using Dev-C++ to invoke your program, you can just open 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 and pause at the current source code cursor location; Click 'Next Step' to step through the code; Click 'Add Watch' to monitor variables.
Setting breakpoints is as easy as clicking in the black space next to 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 do I keep getting errors about 'cout', 'cin', and 'endl' being undeclared?
It has to do with namespaces. You need to add the following line after the includes of your implementation (.cpp) files:
How do I use the C++ string class?
Again, it probably has to do with namespaces. First of all, make sure you '#include <string>' (not string.h). Next, make sure you add 'using namespace std;' after your includes.
Example:
That's it for now.I am not a Dev-C++ expert by any means (in fact, I do not teach C++ nor use it on a regular basis), but if you have any questions, feel free to email me at jaime@cs.uno.edu
Happy coding!
