Note: - If you are using windows 7. And you wallpaper changes after a certain period of time just disable it so as  to run the video as your wallpaper.

Now the process of making the video as wallpaper is
1. Open VLC media player. And press Ctrl + P. It will open preferences.

2. Go to Video tab in the preferences. And there change the setting of output from DEFAULT to DirectX video output.As shown in fig.

One more thing i forgot to tell. Whenever you want to remove the video from your background just refresh your screen and you are done.                                                                                     

Using sleep in dev cpp

Sometime we require a screen to stay for a while and moreover we don't want to use key pressing to move, we just want to use the concept of sleep for a while then its quite easy in dev we just need to write the code :

#include <time.h>

 

time_t now, later;

 

void sleep(int delay)

{

 now=time(NULL);

 later=now+delay;

 while(now<=later)now=time(NULL);

}

 

"TIME.H" comes pre installed with dev cpp. So need not worry about it.

Wherever you want ot use sleep now just call

sleep(2);

here 2 denotes the number of seconds it will sleep for. Keep in mind its seconds not milliseconds.

Now a screen can stay and move whenever you want without using keyboard.

Running C / C++ in Ubuntu

1. Install the build-essential package by typing the following command in the terminal: sudo apt-get install build-essential
2. Now create a file that has the extension .c (if you plan to write a C program) or .cpp (for a C++ program).
3. Write the code in that file.
4. Now open a terminal and go to the place where you saved that file using the cd command (e.g. cd Desktop).
5. If you have a C program type in the terminal 
• gcc -Wall -W -Werror hello.c -o hello.c
• The first line will invoke the GNU C compiler to compile the file hello.c and output (-o) it to an executable called hello.
• The options -Wall -W and -Werror instruct the compiler to check for warnings.
6. If you have a C++ program simply replace gcc with g++ and hello.c with hello.cpp. The options do the same things.
7. If you get a permissions error, you need to make the file executable. You can do this with chmod +x hello.cpp
8. Now type in the terminal ./hello and the program will run.
