Keeping that in mind, we have developed Codebox - a reference to common computer programming problems asked in interviews and examinations. Install it and help comes handy in your preparation for tests, interviews and wherever you require... just one touch away. Programs in sections of string processing, integer manipulation, data structures etc are included.

*** Help us Improve! Take this short survey ***

Codebox Features
* Two most popular programming languages - C and Java.
* Programs are presented in a neat layout with highlighting to make reading easier.
* Distraction free full-screen mode that's easy on eyes.
* Searchable programs
* Program categories for quick access
* Short summary of each problem
* Sample input and output of the programs to help you understand the behaviour.
* The programs can be shared.

Good. Could have been better if there weren't any ads! Hoping to see such an app coming soon, from you, developers! Or probably I'm gonna make my own! :P Anyways, a good app. Not great, but yeah, good.

jatin khurana

Impressive Nice ui . handy. Useful . better utilization of time while traveling .


Awesome and a must have app It's a good collection of programs... Both java and C program.. Fabulous GUI.. And a request to the dev is... Pls add a copy to clipboard option so that it's easy to copy the code and compile it on the phone device ( using some third party compiling apps like C4droid) (Which I do all the time)... Thanks in advance....

Maciek Drozd

These code examples should be taken by students cautiously. There are some mistakes, eg. binary search code doesn't search anything! There is no code convention. Before publishing, it should be revied by programmer.

Smit Modi

Great job appriciated. Keep adding new programs. Will be great if you keep adding more languages like C++ & may be .Net, too

DeKondra ​​​​​

Not bad. Most of the other similar apps are only in c, while this one has java as well. The code is clearly written and easy to read, even though I would have prefered to have it in separate functions instead of putting the code in main. Also has sublime-like view mode, which is awesome. Too bad I found it only after finishing reading everything. Overall, a really nice app for beginner coders ^^

Nitish Kumar

Great app for beginners It has all you need. It has nice interface , useful code , explanation and sample output. It is a great app for beginners.

Abdulkarim Nasir

Like it but Hey thanks for this awesome App..please update it so that we can tick when we're done with a topic...I'll give my 5 stars for that.

Mark Anderson

Good concept Nice idea but needs code review. The Java stack implementation for instance is buggy.

Douglas Nelson

Just a list of reference There is no compiler. Not for those that wish to attempt to program on there phone. 3 stars cause the ref is very nicely laied out.

Monty Paul

Good for beginners ... View is simple and straight forward . no ads thanx to developers. No issues with app running. There is great scope for improvement .... Add some advance programs for startup

Varun Kumar

Really ? Is this an app? I feel this should be a book rather than an app, simply because it does not compile. The topics they have covered is less. One star for the idea and the other for the selection of topics.

Angel Aichu

Excellent:) I love this app. It's easy to use, no bugs with clear explanation of the codes. However, I code with c++ at university for now. Sure I can manage with C but I will be glad if you can add C++ codes. Continue the great job:)

ali mojarrad

Information provided and code do not match. Info are for recursive solutions while code is a simple iterative one. Example: java heapsort

Soumodeb Das

4 star but If u kindly add the optn to add codes by user himself i will give u 5 on 5...

anu reddy manne

Good. Found all algorithm s. Every one must use Must know about algorithms


Love it If youre new to coding.. get it! But if not .. theres really nothing special

Mia Curbow

I Need Help!!!!!! I'm new at this. I'm only fourteen and confused as to how you play this. For example how to get to the place to type the information in. So, if one of you smart people could come to my rescue i would be extremely grateful. I might need a step-by-step guide to understand. Thanks so much.

Janice D'souza

Hats Off.. Really smooth UI.. It contains all the relevant codes that any fresher or engineering student would refer to.. A very handy tool.. Good work guys..

Sathish Kumar

Good in its kind Good ui. Understanding the codes is much easier as a comparision can be made between c n java for d same concept. Overall, a must have one for beginners!

SeiF SaMeH

These are too easy questions to be asked in interviews. Its more like a quick cheat sheet for introductory CS courses. The code is very simple and straightforward both in Java and C.

Tiger Tang

Do you not even know.. There's a method called println!?

Logan Jackson

Good But... This app is good but I have around 5 months experience and this is to confusing.

judson casupang

Good Can you add some basic loopings and the arrays just a college student i didn't explore it yet id just installed it

Moritz Neuhäuser

Nice tool Nice idea, i like it. It would be nice if you could choose the coding problem and switch between different languages for implementation subsequently(not vice versa).

Aamir Qureshi

A must have app for all Bsc.IT Bsc.CS and Software engineering students and professionals. I have just installed this app and not even opened yet but the design of the app speaks about its functionality.....good job guys keep up the good work...!!!!!!

vinit thaker

Mind Blowing!! This is a best app which is out there where you can get all basic programms in various language. And its very simple to use becoz of the user frndly gui

Goodangel Matope

Good for learning This app is fantastic for learning java syntax and also for refreshing even seasoned coders

Vignesh Sharma

Need update Need frequent updates.. Its been a while now. Need an update with more programs

Valentino Pereira

Its soo complex.. Im a technical student and i would like to tell you that this app's programs r very complex.. Ive learned all this at college in much smaller code.. Which is very much applicable

Saket Suman

Superb app Great app with good interface and a good collection of programs

Joseph Garza

Antique It is fine but the only languages it does is c and java

Joshua Bishop

Amazing A really good intro for idiots who don't know what JavaScript and HTML5 is :-)

Nitin karunakaran

Must have app for final year students You need this app if you are going for any interviews in the near future. Simple interface makes it more appealing. (y)

Miklós Galicz

Nice UI, but... The concept is good but I miss JavaScript, php, dart, coffescript, ruby, python....

Virendra Gulhane

Must have App for IT aspirants The best app for revising questions and topics on the go and mean time... Great work by developer team "CodeGuys".

Arushi Doshi

An all-in-one guide to coding in C and Java. I <3 it.

Sachin Shekhar

For beginners! Nothing useful unless you are beginner, but loved the UI.

Dylan Pinheiro

Would be nice if python was included. Still useful though.

Evander Fernandes

Useful reference app Just wish there weren't any annoying ads.

Янек Волощук

Simple calculator Is not working. Fix please.

Иван Литий

good Please, add function for copy the cod

Artem Krimov

Tnx Please add Russian language!!!

Lukas Zimmermann

Bad Java Please do not use this app if you intend to learn Java. This app mostly contains bad Java code. There is seldom a need for separately (meaning on two lines) declaring and initializing a local variable. Why is often everything put into main? Also, please separate the algorithm itself from user interaction if you really want to make things interactively. Perhaps the app is useful for C, I have not checked.

Rouvem Pishchik

Ok There are generic programs for data structures. The code is not perfect though...

Subham Satyajeet

A handy app for the mind. Very neat.

Curu sarn

Useful to have standard algorithms (especially sorts) in your pocket


Codebox Loved a lot .....and it helped me for my studies.... I think you should be adding filesstructures program's that it would be helpful for many of students like me

Arash Dai

Does what it says Some jerk complained about ads. There is one tiny banner ad ive run across, and it doesnt hinder the user in any way. People are so entitled, somebody worked hard on this and youre getting it for free


Stupendous! This app is just great for a newbie, indeed. Or for those who have no clue about what coding is! It explains every basic thing lucidly. Kudos to the creator!

Lema Cices

I thought this was a code viewer/editor app Downloaded it by mistake. I'm going to give you 5 stars for effort and because you tricked me into installing it.

Madhavendra Sharma

Factorial I just checked single program of factorial. Which is mathematically incorrect. App itself mentioned 0! = 1. Does program handle 0! a positive case.

ankit s

An ok app The code can not get compiled, so there may arise some problems for the beginners...nice UI…may be come with some more language options like .net,html

Sina Dehghanian

Fantastic but ... Good but if it has a "FAVORIT BUTTON" to mark codes that we like them or want to use them soon, it would be better

Kevin Topete

Help I cant copy the code wich sucks so yeah but other then good app

Kanishk Jain

Useless You can't actually code in this just read the examples, you took the fun out of it man!!

Mark Swayze

Amazingly useful Just started coding using Java Script, great app, sometimes I feel lost while coding, this app helps me to figure out what's next! Thank you.

Ishan Tiwathia

Add more languages To keep developing further consider adding c++/python/ruby... Its a great refrence tool regardless though. Good job!

David Naulak

Very helpful If c++ is there too. Would be very nice... Vb? Thanks for this wonderful application..


I will rate 5 stare if you add batch
