[majd nicolas]

can we build with c++ an app like whatsapp ?
which library do we use ?

[rabster]

There is no standard library to create apps. If you want to create apps for the iphone I believe objective-C/swift is the way to go correct me if my wrong. And for android devices there is android studio which is in java. There is something called Cocos 2d-X which is in C++ and I believe allows portability between android, PC, iphone, and other platforms. But like I said you are going to have use a 3rd Party library to achieve what you want, or use a different language.

Apps for the Windows store and Android you can write with C++ in Visual Studio, but you need at least Window 8 for it.
