Use system() for clearing the screen. The replacement would be:
system ("clear");
2) Is there any similar kind of replacement for getch() too ?

conio.h is specific to some DOS compilers. Same functionality can be
acheived using ncurse library. Ref:
http://tldp.org/HOWTO/NCURSES-Programming-HOWTO/
Having said that, getch() is a function defined in ncurse library and you
should link the curses library when compiling your program.
After these modifications your program should look like:
****************************************
# include <stdio.h>
void main()
{
system ("clear");
printf("First program using GCC");
getch();
}
****************************************
You compile the program with the following command:
gcc -lcurses -o hello hello.c--
