Time & Place & Event 9:45am ~ 10:35am, Oct. 12, Wednesday ENGR 1.272 Closed-book exam You can take a piece of cheating paper with A4 size Write down whatever that you think is important (on both sides) with any font size

Chapter 1: An Overview of Computers and Programming Languages Computer system has hardware and software Various kinds of languages, such as machine language, assembly, high-level Algorithm: step-by-step problem-solving process; solution in finite amount of time Object-oriented design (OOD): a program is a collection of interacting objects C++ is an object-oriented programming language

Chapter 2: Basic Elements of C++ Special symbols, keywords, rules of identifiers Basic data types int, float, double, char, string Operators Arithmetic operators and their precedence +, -, *, /, %, +=, -=, *=, /= Increment/decrement operator ++, -- Declaration of variables int first=13, second=10; char ch=' '; Input/Output statement cin and cout

Chapter 3: Input/Output Declaration of input/output stream Usage of cin and cout (as well as other istream/ostream variables) The stream extraction operator, cin>> Syntax and meaning of functions cin.get(varChar); cin.ignore(intExp, chExp); cin.putback(ch) cin.peek(ch) getline(cin, str); See examples in lecture slides

Chapter 3: Input/Output (cont'd) The stream insertion operator, cout<< endl setprecision, showpoint, setw, setfill File stream Header: fstream

Chapter 4: Control Structures I (Selection) Relational operators and precedence Comparison operators <, <=, >, >=, ==, != String comparison Logical operators &&, | | Evaluation of logical expression See examples in lecture slides

Chapter 4: Control Structures I (Selection, cont'd) Syntax and usage of the selection structure One-way selection: if () { } Compound statements Two-way selection: if () { } else { } Multi-way selection: switch () { } Nested if statement See examples in lecture slides

Chapter 5: Control Structures II (Repetition) Repetition structure count-controlled sentinel-controlled flag-controlled EOF-controlled Syntax and usage of the while statement

Good Luck! Q/A
