  40. 40. C C Almost half-century of existence (1969) Used by virtually all Operating Systems (and Windows) UNIX (Recoded to C in 1973) “You shoot yourself in the foot.” (programmers to programmers) Why? Low-level Pointers, DMA, etc. It’s not portable! It’s true, but not 100% true F###### fast! (this is why games are developed on it!) “If you do something easily in C, probably it’s wrong.” (me) PS: C++ is a superset of C (OO joke: Why don’t C++ talk to C?)
