20. Note !! • Slide one 1-15 demonstrated the general contents of the CIS-165 Course in “plain English” • What does that mean in C++ ??

21. C++ UP_FRONTNO Surprises !! • Data types: • integers, real (float), long, short, char, string. • Declaration: • int var1 • float var2 • Char z • . • .

22. C++ • Library functions such as: sqrt( ), pow( ). • Input such as : cin >> , cin.getline( ) • Output such as: cout << • Formatted output setw( )

23. C++ • Operators: >, <, =, != … • Logical : and &&, or || • Boolean (True and False) • if else statement if (x > y) z=0; else z=1;

24. C++ • Switch and case: switch(var) { case 1: codes to execute. break; case 2: codes to execute. break; }

25. Do while do { stat1; stat n; } while (condition true);

26. While stat. While (condition true) { stat 1; stat n; }

27. Input validation if(cin.fail()) • For stat. For (i=0; I < 100; i++) { stat 1; stat n; }

28. One D Array int MyArray[5]= {1,2, 4, 6,8} Char My_Chr_Array [ ]={‘a’, ‘b’, ‘g’,’\0’} • typedef typedef unsigned short int USHORT; USHORT width, height, length;

29. Constants (also called literals) Defining constants with const: const unsigned short int Stu_Per_Class =10; • Defining constants in traditional way: #define studentsPerClass = 10; • Symbolic Const. students = classes *15; • Enumerated const: enum Color {Red, Blue, White, Black};

30. White space X= a + b; Or as X = a + b ;
