Do you know that you can run c/c++ console application on your android device? If not, then this a thread for you.
what is a console app?
Console app is simply an application that you control with a keyboard input. It doesn't have any eye catching graphical user interface (gui).

whats the point of running an app that does nothing graphicaly interesting?
1. For educational purpose.

2. Easy to programme and execute.

3. Memory efficiency.

4. speed of execution ..etc


what do I need to begin?
1. A rooted android device. I am using gtn7100 (android 4.1.1), I haven' tried this on any other device so I can't assure you how this tutorial will behave on other android devices, but feel free to experiment.

2. X-plore file manager. you can download it from playstore or mobogenie. after you download and install it, open it, hit the menu key ●●-> configuration ●●-> root access ●●-> superuser + mount writeable.
***I advice you to set app password coz this app can do wonders in the hands of an inexperienced operator*****


3. busybox. this is optional but use full. also dowload via mobogenie or playstore. some utility programs for command line.


4.terminal emulator. download via mobogenie or playstore. for running your console app via command line.

5. cppDroid. download via mobogenie or playstore.
this is the app that you code and compile ur c/c++ program with. it comes with a built in code editor.

6. Hacker's keyboard. this app make is easy to type like you are using a full computer keyboard.


and you are good to go.

**** ********
* ask me questions if u are stuck *

this is a simple program that prints fibonacci sequence from '1 to n', where n is a number (interger) passed via command line.
for example to compute fibonacci 1 to 50, I simple type in my terminal emulator something like this::

fibmem 50 ** then ENTER KEY**

where fibmem is an app that a compiled with cppDroid, and moved it to system/bin with my X-plore file manager. and 50 tells the program to compute fibonacci 1 to 50. fibmem, the 'mem' stands memoized fibonacci which is magically fast I tell you.

//fib function

double fib( int n) {
double f;
if(mem[n] )
return mem[n];
if( n <= 2)
f = 1;
else
f = fib(n-1) + fib(n-2) ; //recursive call to fib()
mem[n] = f;
return f;
}
