TAILIEUCHUNG - Lecture Visual programming: Chapter 6 - Muhammad Bilal Zafar

This chapter presents the following content: Attributes, translation schemes, postfix notation, synthesized attributes, tree traversals, translation schemes, preorder and postorder traversals. | LESSON 06 Overview of Previous Lesson(s) Over View Interactive development environment is a software application that provides comprehensive facilities to computer programmers for software development. Microsoft Visual Studio is an integrated development environment (IDE) from Microsoft Corporation based on .Net framework 3 Over View C++ Keywords Reserved words Identifiers Programmers defined variables Variables A named storage location in the computer’s memory for holding a piece of data. Data Types When computer programs store data in variables, each variable must be assigned a specific data type. Some common data types include integers, floating point numbers, characters, strings, and arrays. 4 Over View. Looping structures For loop While Do While Decision structures If If / else Switch 5 Over View. Operator Precedence Operator precedence orders the operators in a priority sequence. In an expression with more than one operator, evaluate in this order: - (unary negation), in order, left to right * / %, in order, left to right + -, in order, left to right Example expression 2 + 2 * 2 – 2 6 evaluate first evaluate second evaluate third Over View Type Conversion and Casting Implicit type conversion: When an expression involving variables of different types then for each operation to be performed, the compiler has to arrange to convert the type of one of the operands to match that of the other. Any pair of operands of different types, the compiler decides which operand to convert to the other considering types to be in the following rank from high to low: 7 Over View Explicit Type Conversion: A forced conversion from one type to another is referred as explicit type conversion. Auto keyword is used as the type of a variable in a definition statement and have its type deduced from the initial value. auto n = 16; // Type is int auto pi = ; // Type is double auto x = ; // Type is float auto found = false; // Type is bool 8 Over View Bitwise .
