I am just beginning to learn C programming. I am going to buy the most popular textbook on it and learn. When I was reading about how C programming works, I was told that once you write your C program, you must run it through a C compiler to turn your program into an executable that the computer can run (execute). Apparently, since macs are Unix-based, there is a c compiler included on my mac. Is this true? If so, how do I use it? It said that the C compiler on Unix machines is called either "cc" or "gcc" and is available on the command line. What's that about? Please help soon! Thanks!
