11. The C Programming Language A programming language specifies the words and symbols that we can use to write a program A programming language employs a set of rules that dictate how the words and symbols can be put together to form valid program statements The Java programming language was developed in the 1970’s at Bell Labs It is one of the most popular and powerful programming languages used today.

12. Reserved Words in C auto break case chart const continue default do double else enum extern float for goto if int long register return short signed sizeof static struct switch typedef union unsigned void volatile while

13. Reserved Words in Java abstract boolean break byte case catch char class const continue default do double else enum extends false final finally float for goto if implements import instanceof int interface long native new null package private protected public return short static strictfp super switch synchronized this throw throws transient true try void volatile while

14. Focus of the Course This is an intro to problem solving and programming class (that uses the C programming language) The focus is on  problem solving  the logic of programming  program design, implementation, and testing  The fundamentals of programming

15. What this class will NOT cover We will not go into details of programming GUIs We will not cover many of the advanced programming concepts in C We will not cover many of the stantard functions and libraries that come with C We will not cover object oriented programming (C++)

16. This is not…

17. Warning Learning how to program takes a lot of time! It also requires a lot of patience. You cannot learn how to program by just reading the textbook. You have to spend long hours in front of the computer. If you want to learn how to program well you will have to take at least 2-3 other programming classes as well. This class alone is not enough!

24. First Program

25. C Program Structure int main(int argc, char* argv[]) {}{} #include // comments about the program printf(“Hello World! \n”); return 0;

26. C Program Structure int main(int argc, char* argv[]) {}{} #include All programs must have a main function

27. C Program Structure int main(int argc, char* argv[]) {}{} #include main function body Comments can be placed almost anywhere

28. C Program Structure int main(int argc, char* argv[]) {}{} #include // comments about the program printf(“Hello World! \n”); return 0;

29. Java Program Structure public class MyProgram {}{} // comments about the class public static void main (String[] args) {}{} // comments about the method System.out.println(“Hello World!”);
