tailieunhanh - Lecture C++ programming: from problem analysis to program design - Chapter 3: Input/Output
In this chapter, you will: Learn what a stream is and examine input and output streams; explore how to read data from the standard input device; learn how to use predefined functions in a program; explore how to use the input stream functions get, ignore, putback, and peek; | C++ Programming: From Problem Analysis to Program Design, Fourth Edition Chapter 3: Input/Output C++ Programming: From Problem Analysis to Program Design, Fourth Edition Objectives In this chapter, you will: Learn what a stream is and examine input and output streams Explore how to read data from the standard input device Learn how to use predefined functions in a program Explore how to use the input stream functions get, ignore, putback, and peek C++ Programming: From Problem Analysis to Program Design, Fourth Edition Objectives (continued) Become familiar with input failure Learn how to write data to the standard output device Discover how to use manipulators in a program to format output Learn how to perform input and output operations with the string data type Become familiar with file input and output C++ Programming: From Problem Analysis to Program Design, Fourth Edition I/O Streams and Standard I/O Devices I/O: sequence of bytes (stream of bytes) from source to . | C++ Programming: From Problem Analysis to Program Design, Fourth Edition Chapter 3: Input/Output C++ Programming: From Problem Analysis to Program Design, Fourth Edition Objectives In this chapter, you will: Learn what a stream is and examine input and output streams Explore how to read data from the standard input device Learn how to use predefined functions in a program Explore how to use the input stream functions get, ignore, putback, and peek C++ Programming: From Problem Analysis to Program Design, Fourth Edition Objectives (continued) Become familiar with input failure Learn how to write data to the standard output device Discover how to use manipulators in a program to format output Learn how to perform input and output operations with the string data type Become familiar with file input and output C++ Programming: From Problem Analysis to Program Design, Fourth Edition I/O Streams and Standard I/O Devices I/O: sequence of bytes (stream of bytes) from source to destination Bytes are usually characters, unless program requires other types of information Stream: sequence of characters from source to destination Input stream: sequence of characters from an input device to the computer Output stream: sequence of characters from the computer to an output device C++ Programming: From Problem Analysis to Program Design, Fourth Edition I/O Streams and Standard I/O Devices (continued) Use iostream header file to extract (receive) data from keyboard and send output to the screen Contains definitions of two data types: istream - input stream ostream - output stream Has two variables: cin - stands for common input cout - stands for common output C++ Programming: From Problem Analysis to Program Design, Fourth Edition I/O Streams and Standard I/O Devices (continued) To use cin and cout, the preprocessor directive #include must be used Variable declaration is similar to: istream cin; ostream cout; Input stream variables: type istream .
