Hahahah C is dead? Come on, don't start that kind of bating. High-level efficiency-oriented languages are high-level efficiency-oriented languages and low-level performance-oriented languages are low-level performance oriented languages. This has been true and will continue to be true. Notice the number of high-level languages that have waxed and waned while C has continued to flourish...
C is almost dead on Android, with its minimal exposure on the NDK and I hope Google does not change its mind about it.
C is now being killed on MacOS X and I look forward to Swift's success.
So this leaves out the embedded industry (slowly moving to Ada and Java on IoT) and the hardcore UNIX guys.
