Linux Howto: Missing curses/ncurses Library Ubuntu 12.04

So I tried this simple program to test a Text-screen based program on my Ubuntu 12.04:

mrinal@ms-dell:~/C_Progs$ cat screen1.c 
#include <unistd.h>
#include <stdlib.h>
#include <curses.h>

int main()
{
initscr();
move(5,15);
printw("%s","Hello World");
refresh();
sleep(5);
endwin();
exit(EXIT_SUCCESS);
}

When I try to compile it using the Text-screen library system curses, I get the following error:

mrinal@ms-dell:~/C_Progs$ gcc screen1.c -o ans -lcurses
screen1.c:3:20: fatal error: curses.h: No such file or directory
compilation terminated.

Turns out I dont have the curses.h header file (nor the new ncurses.h)
mrinal@ms-dell:~/C_Progs$ ls -l /usr/include/*curs*
ls: cannot access *curs*: No such file or directory

This means the packages for curses (and/or ncurses) library are missing. To fix this, I did this:

mrinal@ms-dell:~/C_Progs$ sudo apt-get install libncurses5-dev libncursesw5-dev

After this, the curses header file is now available in my /usr/include directory:

mrinal@ms-dell:~/C_Progs$ ls -l /usr/include/*cur*
-rw-r--r-- 1 root root  6582 Nov 18  2011 /usr/include/cursesapp.h
-rw-r--r-- 1 root root 27630 Nov 18  2011 /usr/include/cursesf.h

-rw-r--r-- 1 root root 12534 Nov 18  2011 tic.h

-rw-r--r-- 1 root root  3108 Nov 18  2011 unctrl.h

And the program compiles successfully:

mrinal@ms-dell:~/C_Progs$ gcc screen1.c -o ans -lcurses

And executes successfully too.

mrinal@ms-dell:~/C_Progs$ ./ans
