Welcome back!

1. My problem is i configured the build-essential(for c compilation).
and I am unable to get the output.This is what i do.(check the image)

The image is too small to be readable and too fuzzy when blown up. (My eyes are old.) Perhaps you could provide a little more detail about the problem. For example, I don't know what "unable to get the output" means. Post your commands and the resulting errors or output between CODE tags.

Your second item is complete Greek to me (I'm not Greek). In most Linux desktop environments, pressing the middle mouse button will copy highlighted text from one window to the cursor location in another window, but I don't know if that has anything to do with what you're trying to do. If that's not working for you, you can try Edit, Copy when the desired item or text is highlighted and then Edit, Paste when the cursor is positioned where you want to place the copied object. More info would be useful. Maybe you're trying to copy text from one console window to somewhere else. Detail the source and desired destination.

3. How can i run JAVA programs.

I believe your Ubuntu install includes the Open Java Runtime Environment (JRE), but it may not include the Java Development Kit (JDK). So, if you want to run existing Java programs, you should be able to by either selecting (double clicking) the Java executable or by the terminal command:

> java javaprogname

If you need to compile Java source code, then search your repository (software installation) for JDK and install that, if not installed already.

Again, more info would be helpful. If you're getting errors because your browser isn't configured correctly to run Java, that's different. But I can't tell what the problem is from the info you've provided.

5. I lost my time display from the taskbar. How can i bring it back

I recommend you start separate threads for each new problem rather than creating long lists that keep changing. Questions posed in lists get lost and not answered.

I don't have an Ubunto OS handy on which to try out a solution, but try right-clicking on the taskbar and selecting "configure" or "properties" or a similarly named menu item to add the time widget (whatever it's called) back.

4. Thank you for your help.

I can't really read what you're doing in the image, but I know the answer to question 3.
For a java class file:

java file.class

and for a jar file:

java -jar file.jar

you can also right click and choose the java runtime environment to open the file with and it'll be executed.

It's a compilation error, not something wrong with your underlying system. We can't help you more without the actual code in your first.c file.

[bunty82]

#include<stdio.h>
#include<conio.h>

void main()
{
int a,b,S;
printf("enter two numbers a and b" );
scanf("%d%d",&a&b );
S=a+b;
printf("the sum is %d",S );
getch();
}


this is a simple program. i was trying to test.

[rcgreen]

conio.h is for console input and output in msdos.
You will need to rewrite your code to work without it
or research the use of the curses library for
similar functionality.

working with C in linux i have to start working on different command lines.
