C is a well known Programming language Created by Dennis Ritchie between 1969 and 1973 at Bell Labs, since then it has become one of the most widely used Programming Language of all time.
It is usually used for low level Programming such as developing Operating Systems, Drivers, well as various application software for computers ranging from supercomputers to embedded systems.
The language has become available on a very wide range of platforms, from embedded microcontrollers to supercomputers.
Android is based on Linux Kernel so it's definitely possible to compile & run C/C++ programs on Android.
C is quite cross-platform , so a C Program written in Windows can Run on Linux ( and android ) and vice versa.
Special Note : You might be wondering why i included C++ where we should be only focusing on C.
The Reason is, C++ was actually developed as a superset of C Programming Language, and nowadays nobody builds a compiler specific for only C. So a compiler for C can also compile C++ programs
If You're New To C Programming or want to start learning C Programming , i recommend reading our article, Baby Steps in C Programming
So With Further Talking Let's Jump into to find ways to run C/C++ Programms in Android

CppDroid from Play Store
{: .crtx}
If you want a full C/C++ Development workspace , I recommend using CppDroid.
But right Now there's one down point about it, It's not been updated in Play Store since 17 August,2017
Install it From : Play Store
Visit Their Official Website : https://www.cppdroid.info
#3 Termux
Termux, the all-in-one solution which was also mentioned on our previous article , Python For Android - Run Python Programs in Android
As also mentioned in previous article, it's a terminal emulator for Android which means with help of it we can run any linux (almost any 😉) programs on Android.
termux.com
{: .crtx}
To Install and Use C/C++ compiler in Termux (in Termux clang is the C/C++ compiler) ,
- Download & Install Termux from : Play Store
- After Installing execute this command
pkg install clang - After Successfully installing
clangyou can compile C/C++ scripts.
Example :
clang hello.c
After you'll get an executable a.out which you can run using ~$./a.out
To edit and create C/C++ Scripts you can use VIM inside termux which can be installed with
pkg install vim
Or, you can use QuickEdit
If you're new to the world of programming and never used Command Line Applications I wouldn't recommend you to use Termux , use CXXDroid or CppDroid instead.

Is it possible to make this for an unrooted device?
Yes ofcourse. But still Root gives you more flexibility
There is a problem for me. I am storing my files on sdcard because the device is unrooted. When I type in Termux 'clang filename.c' or 'clang filename.c -o filename', and enter, I have as result '$', no more. But I noticed that if there is an error in code, I have an error message.
It seems strange but one time the code were compiled.
I don't understand what is the problem.
Maybe it had Runtime Errors
I don't understand
Can you share the source code of your program.
Runtime error are such type of error which can't be detected by compilers, and such error can be noticed while running the program
I tried even the simplest code as hello world. It's running perfectly with Dcoder app.
But not compiling with Clang?
Exactly
What error does it give?
No error but doesn't compile
there must be something to identify the problem, without knowing the bug I can't help you to debug it.
Here is a pasted text from Termux
$ gcc -o mult.cclang-8: error: no input files
$ clang -o mult.c
clang-8: error:
Ah, seems your source code is not in Termux home path. You should copy your
mult.cfile to Termux home directoryHow can I make this?
Copy - paste
$ clang -o condition.cclang-8: error: no input files
$ cd
$ ls
Filename eaain herbe.rb
conditiond.c eaain.c termux-sudo
downloads essain.c
$ pwd
/data/data/com.termux/files/home
$
And this is in the path, right?
Ah now I understand.
Just Remove
-oand it should work fine.Do this
clang condition.cI reinstalled Termux, clang and nano to write files. I wrote and saved a file in rb and a file in C. Note that I wrote in the Termux path and here is the result.I can run easily Ruby files but for c I don't reach out the expected result.
Setting up ruby (2.6.5) ...$ nano simple.rb
$ ruby simple.rb
hello
$ nano simple.c
$ nano simple.c
$ clang nano.c
clang-8: error: no such file or directory: 'nano.c'
clang-8: error: no input files
$ clang simple.c
$ clang simple.c -o simple
$ ls
a.out downloads simple simple.c simple.rb storage
$ clang simple.c
$ clang -o simple.c
clang-8: error: no input files
C is a compiled language and It seems
simple.cis compiled.Just Run the binary
simplewith$ ./simpleIt works! So, if I understand, after the clang action, A compiled file is created, and I need to open it with prompting it, the same name of file without the ".c" at the end of the name. And to make this I need to type "./filename". Right?
Partially.
Look, C is a compiled langauge, and Clang is a compiler unlike Python or Ruby which are interpreted language.
When you type the command
clang simple.c, clang takes the source code and compiles it into machine code intoa.out(a.outis default output name) and to run the program you must execute the binary like this$ ./a.outAnd you can name the output binary anything you like by simply passing the
-oflag, the syntax is like this :$clang <SOURCE_CODE> -o <OUTPUT_NAME>@koouty , seems like you're new to C , I would recommend watching some Beginners' Tutorial and Reading some tutorials available on internet.
Many many thanks.
If any need any further help you can just DM me

I understand, but it wouldn't be a problem if you want to do some quick prototyping or experiment some little bit.
I wrote this article because a few years ago, I didn't have a computer just an android phone. I started learning to programme using the apps I mentioned above.
I hope above apps will be useful for people who don't have access to computers or want to do some quick prototyping.
Termux is amazing - I went on a business trip a while back and we got production error emails on a snowy back road in the middle of nowhere. I was able to ssh into the server, grep the log for the error, and push a hotfix with vim over mobile data. The team stopped making fun of me for programming on my phone after that.
I used TerminalIDE on my older rooted Galaxy S3, when Termux wasn't avail for that version (too lazy to re-root). I downloaded CPPDroid, stole the compiler, and modified it to work in the terminal so I could work on my C game at the time using vim. I spent a lot of time commuting to school, so I felt it was a better use of the time.
I still find it amazing that my new phone is more powerful than my old netbook I used to use in school, and invaluable to have a pocket *nix device with me at all times. I even set up a headless driver for ssh web dev on the fly. You get used to the tiny keyboard in time, most people just expect typos in my texts now...
Yeah, you need tiny fingers, but on a Pixel XL it's not the worst
Your experience was great. I remember last year I compiled the whole metasploit framework for Android (thanks to Termux) and it worked perfectly on multiple android devices. 😀
Termux is awesome indeed and we here at Andronix love it. Andronix is an open-source, completely ad-free app that lets you install full-fledged Linux distributions on your non-rooted Android device. We utilize the power of Termux 💙.

Installing Linux on your Android Device

Will you please share how you had done that?
Stealing the compiler, or ssh'ing over data?
Either way - same answer. These days I use the Termux app (IIRC not available on iPhone), within which you can install openssh and the gcc toolchain which will allow you to ssh and build c programs just as you would on a nix terminal on any desktop.
When I stole the compiler, I had a rooted phone, installed the C4droid app, then went into it's package folder and looked for the binary and linked lib files, copied those into my home folder, made a small wrapper script that added all the necessary compiler flags, and built the c apps from the TerminalIDE terminal.
It's significantly more work (plus trial and error) doing it that way, and requires rooting your phone. Now, with Termux, it's a simple
apt-get install -y build-essentials make gcc ...andapt-get install -y openssh-{client,server}.EDIT: found the old script - left the comments for myself
Hey Palash, that was a great list indeed. But how about running a dedicated IDE for C on your non-rooted Android device? Andronix allows you to do just that in a few clicks.

Hey Palash, Firstly Kudos to you for making this great app.. I have a project wherein I need to integerate C compile with my android app within Android studio.. is it possible? I would be grateful could you suggest some hints for the same..
$ apt install clang
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package clang is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'clang' has no installation candidate

Hey so I haven't programmed in a very long time last time I did was programming in C using windows api. Would I be able to write my C code using windows api and it still run on Android? Sorry if its a stupid question
If not how would I create the interface? Sorry im so old lol if you can point me in the right direction that would be great.
Thank you so much. This is very helpful to me
I tried to install the package of clang in termux but this message showed to me: "unable to locate package clang"
How can i fix this ?
