Answer 1

This should be corrected fairly easily via the graphical user interface. No command or file modification should be necessary. In Nautilus you can right click on the file to open.

To run a C program you need to compile it first, generate an executable and then run it as a normal system command. You cannot run it directly from Notepad++ because as such, it is not still executable. This is generally done with a program called a C compiler (which you don't mention if you have one or not) I figure that you are on a Windows computer, so the variety and availability of C compilers makes it impossible to continue giving you advice. You need to install a compiler, learn how to use it, and then you'll know how to make your C program executable in the system.

I recommend you to read a good programming book in C, like "The C Programming Language" from Brian Kernighan & Dennis Ritchie, to know how to compile a program and your operating system's manual to know how to execute a program.

Edit

Oh, sorry, you said on linux. You have to save your source file (with some name ended in .c) then compile it with something like

$ cc my_hello.c -Wall -o my_hello

where my_hello.c is the name you gave to the C source file, -Wall makes the compiler to be more verbose in explaining your C programming errors and -o my_hello specifies the compiler to output the executable command in a file called my_hello.

(I have represented the system prompt as $ and the screen cursor as _, you don't need to key those symbols) and then

$ my_hello
Hello$ _

(as you didn't end the line with \n, the next system prompt will appear next to your program's last message) to get it printed correctly, just modify your program to appear as

#include <stdio.h>
int main()
{
    printf("Hello\n"); 
    /*           ^^-- insert the '\n' there */
}
