• Source code is the human-readable form of the program, stored in a text file
• Object code is the executable form of the program created by the compiler
• Typing in the programs yourself often helps you remember key concepts
• When entering a program by hand, use a text editor, not a word processor
• C++ programs are normally contained in files that use the .cpp extension
• The output from a C++ compiler is executable object code
• The executable file will use the same name as the source file, but have the .exe extension
• After a C++ program has been compiled, it is ready to be run
• The main() function is where program execution begins and ends
• cout << "C++ is power programming."; is a console output statement
• The message “C++ is power programming.” is a string in C++
• return 0; terminates main() and causes it to return the value 0 to the calling process
• All C++ statements end with a semicolon
• If you enter something incorrectly into your program, the compiler will report a syntax error message when it tries to compile it
• C++ is the preeminent language for the development of high-performance software
• C++ syntax has become the standard for professional programming languages
• C++ design philosophy reverberates throughout computing
• C++ is the language from which Java and C# are derived
• To be a professional programmer implies competency in C++
• C++ is an "object-oriented" programming language created by Bjarne Stroustrup in 1979
• Initially called "C with Classes", the name was changed to C++ in 1983 and released in 1985
• C++ maintains aspects of the C programming language but has features that simplify memory management
• C++ could be considered a superset of C, and C programs will run in C++ compilers
• Structured programming consists of simple, hierarchical program flow structures
• Sequence: refers to an ordered execution of statements
• Selection: one of a number of statements is executed depending on the state of the program
• Repetition: a statement is executed until the program reaches a certain state or operations are applied to every element of a collection
• The need for C++ arises from the increasing complexity of programs
• C++ is the response to the need for better ways to manage program complexity
• C++ helps programmers comprehend and manage larger, more complex programs
• C++ is the parent language for Java and C#
• Syntax for C++, Java, and C# is nearly identical
• C++ is used for high-performance software, Java and C# for highly portable software
• Java and C# create cross-platform, portable programs, while C++ is tied to a specific CPU and Operating System
• Java and C# achieve portability by compiling a program into a pseudocode, intermediate language
• Bytecode is the intermediate language for Java, and Microsoft Intermediate Language (MSIL) is for C#
• Pseudocode is an artificial and informal language that helps programmers develop algorithms
• Pseudocode is a "text-based" detail (algorithmic) design tool
• Pseudocode includes keywords such as while, do, for, if, switch
• Pseudocode is executed by a runtime system
