10. int main
int main() {
Statements;
return 0; }

11. void main
void main() {
Statements;
return; // not always necessary }

12. Pseudocode
BEGIN / START
statements
END / STOP

13. Data Types Unsigned / Signed Interger types
short int
int
long int
char
Real / Floating Point types
float
double
long double

14. Variable Naming Scheme
See Page138 in Manual.
(Very, very, very important)

15. Variable Declaration Data-type variable-name //comment
int score;//holds student score
double rate;//holds interest rate
char opselect;//holds control character

16. Pseudocode DECLARE AS INTEGER score DECLARE AS DOUBLE rate
DECLARE AS CHAR opselect

17. Variable Initilization
Data-type variable-name = value//comment
int score = 0;//holds student score
double rate = 3.5;//holds interest rate
char opselect = ‘x’;//holds control character
Const int votingAge = 18;//legal voting age

18. Pseudocode DECLARE AS INTEGER score, SET AS 0
DECLARE AS DOUBLE rate, SET AS 0.0
DECLARE AS CHAR opselect, SET AS ‘x’

19. Output PRINT “Hello World!!” Display “Hello World!!”
cout<<“Hello World!!”;
cout<<“Hello World!!”<<endl;
Hello World!!

20. PRINT “I am ” age “ years old.”
cout<<“I am ”<<age<<“ years old.”<<endl;
I am 5 years old.

21. Input READ num1 READ num1, num2 cin>>num1;
cin>>num1>>num2;

22. Escape Characters
See page 129.

23. Arithmetic Addition(+); Subtraction(-); Multiplication(*);
Division(/);
Modulus(%).

24. receiving-variable = variable operator variable
