• C is a procedural language, not object-oriented.
• Both C and Java are imperative. They contain series of instructions on HOW to compute something, not just what to compute.
• The first C standard was C89 (1989/1990-ish).
• Features of C can be hardware-dependent. For example, the capacity of int can be limited depending on the machine compiling/running the code.
• Weaknesses of C: less security, large projects are difficult to manage.
• The main function has a return type of int. Exit status code of 0 is a success.
• There are three standard streams: standard input, standard output, standard error.

  	#include <stdlib.h>	// To access standard library
  	#define PI 3.14	// To define macro
  
  	void some()
  	{
  		exit(0);	// Exit with status 0, outside of main function
  	}
  
  	int main()
  	{
  		return EXIT_SUCCESS;	// return 0, part of standard library
  		// return EXIT_FAILURE;	// return 1, part of standard library
  	}
