What is the predominant programming language used for the F35 Lightning II aircraft?

Question

I understand ADA was used for the F22. What is the principal language for the software on the F35?

Answer 1

The F-35 Joint Strike Fighter (Lightning II) software was comprised of the following languages (at least according to the source below):

Source | Source - Alt (page 38)

This shows:

• 7% Assembly,
• 5% Ada 83,
• 35% C++, and
• 53% C.

I think Wikipedia's statement is slightly incorrect. All new development for the F-35 was done in C or C++. According to the source above:

In almost every case, the same decision to use C or C++ was made except when a large amount of reuse was possible from previous (F-22) developments.

EDIT 2016-03-10: The main source is dead and I haven't found a new one.
