Projects for computer languages

 I think one should learn C++/C+/C/C Turbo this will help you in your future plus some projects related to it are :
you can make app out of it for android phone, iPhone blackberry and for iOS and windows XP,7&8
some app examples are
media players
games
apps that send daily e-mail regarding a topic on subscription .
for other apps see the google app market or the iapps as i cannot tell everthing here in detail it will be too long
JAVA
you can make the same apps out of JAVA that you can make with the C language family so it is your choice you can make a app with the language you are comfortable with.
HTML
if you know nice html you can make a nice website some projects are:
Business sites
game sites
news sites
educational sites
music sites
the once which mostly become successful are music and game site easy to make and large profit margins.
html 5 also helps you in making apps with JAVA and C family
you of course can't make any of the sites above without CSS, PHP AND JAVASCRIPTS
I SAY THAT IF ONE DOES A JAVA OR C PROJECT THEN
MAKE A GAME OR ANY OTHER ADVANCED APP OF A APP IN THE GOOGLE MARKET AND THEN PUBLISH IT ON THE PLAY MARKET IF YOU DO A HTML PROJECT THEN
MAKE A GAME OR MUSIC WEBSITE .
