Document Summary

C is a programming language -- one of the world"s most used. It was stable and established in the 1970s. It is used to build a huge number of software systems including unix, windows, the internet, robotics smart phones. Unix wasn"t initially built in in c (it pre-dated it) but it was recoded into it. C is up a level of abstraction than low-level assembly codes. You don"t need to think about the processor underneath. It was a tool that let you write more abstract code . Eg, don"t need to think about how things are saved in memory (if 6 should be saved as an int or double , eg). Today, when you want to control low-level things, you use c. Printf ( hello world. \n ); printf( thank you for providing me with %d arguments. \n , argc ); printf( my favorite is argument %s. \n , argv[argc-1] );
