Chapter 7 Expressions and Assignment Statements
Chapter 7 Expressions and Assignment Statements Chapter 7 Topics Introduction Arithmetic Expressions Overloaded Operators Type Conversions Relational and Boolean Expressions Short-Circuit Evaluation Assignment Statements Mixed-Mode Assignment Chapter 7 Expressions and Assignment Statements Introduction Expressions are the fundamental means of specifying computations in a programming language. To understand expression evaluation, need to be familiar with the orders of operator and operand evaluation. Essence of imperative languages is dominant role of assignment statements. Arithmetic Expressions Their evaluation was one of the motivations for the development of the first programming languages. Most of the characteristics of arithmetic expressions in programming languages were inherited from conventions that had evolved in math. Arithmetic expressions consist of operators, operands, parentheses, and function calls. The operators can be unary, or binary. C-based languages include a ternary operator, which has three operands (conditional expression). The purpose of an arithmetic expression is to specify an arithmetic computation. An implementation of such a computation must cause two actions: o Fetching the operands from memory o Executing the arithmetic operations on those operands. Design issues for arithmetic expressions: 1. What are the operator precedence rules? 2. What are the operator associativity rules? 3. What is the order of operand evaluation? 4. Are there restrictions on operand evaluation side effects? 5. Does the language allow user-defined operator overloading? 6. What mode mixing is allowed in expressions? Operator Evaluation Order 1. Precedence The operator precedence rules for expression evaluation define the order in which “adjacent” operators of different precedence levels are evaluated (“adjacent” means they are separated by at most one operand). -

Understand the operator precedence and type conversion And write mathematical functions. 3.1 Introduction Java supports a rich set of operators. We have already used several of them, such as =, +, –, and *. An operator is a symbol that tells the computer to perform certain mathematical or logical manipulations. Operators are used in programs to manipulate data and variables. They usually form a part of mathematical or logical expressions. Java operators can be classified into a number of related categories as below: 1. Arithmetic operators 2. Relational operators 1 3. Logical operators 4. Assignment operators 5. Increment and decrement operators 6. Conditional operators 7. Bitwise operators 8. Special operators 3.2 Arithmetic Operators Arithmetic operators are used to construct mathematical expressions as in algebra. Java provides all the basic arithmetic operators. They are listed in Tabled 3.1. The operators +, –, *, and / all works the same way as they do in other languages. -
Operator Overloading ______
Chapter 10: Operator Overloading _________________________________________________________________________________________________________ Consider the following C++ code snippet: vector<string> myVector(kNumStrings); for(vector<string>::iterator itr = myVector.begin(); itr != myVector.end(); ++itr) *itr += "Now longer!"; Here, we create a vector<string> of a certain size, then iterate over it concatenating “Now longer!” to each of the strings. Code like this is ubiquitous in C++, and initially does not appear all that exciting. However, let's take a closer look at how this code is structured. First, let's look at exactly what operations we're performing on the iterator: vector<string> myVector(kNumStrings); for(vector<string>::iterator itr = myVector.begin(); itr != myVector.end(); ++itr) *itr += "Now longer!"; In this simple piece of code, we're comparing the iterator against myVector.end() using the != operator, incrementing the iterator with the ++ operator, and dereferencing the iterator with the * operator. At a high level, this doesn't seem all that out of the ordinary, since STL iterators are designed to look like regular pointers and these operators are all well-defined on pointers. But the key thing to notice is that STL iterators aren't pointers, they're objects, and !=, *, and ++ aren't normally defined on objects. We can't write code like ++myVector or *myMap = 137, so why can these operations be applied to vector<string>::iterator? Similarly, notice how we're concatenating the string “Now longer!” onto the end of the string: vector<string> myVector(kNumStrings); for(vector<string>::iterator itr = myVector.begin(); itr != myVector.end(); ++itr) *itr += "Now longer!"; Despite the fact that string is an object, somehow C++ “knows” what it means to apply += to strings. -

Parsing Arithmetic Expressions Outline
Parsing Arithmetic Expressions https://courses.missouristate.edu/anthonyclark/333/ Outline Topics and Learning Objectives • Learn about parsing arithmetic expressions • Learn how to handle associativity with a grammar • Learn how to handle precedence with a grammar Assessments • ANTLR grammar for math Parsing Expressions There are a variety of special purpose algorithms to make this task more efficient: • The shunting yard algorithm https://eli.thegreenplace.net/2010/01/02 • Precedence climbing /top-down-operator-precedence-parsing • Pratt parsing For this class we are just going to use recursive descent • Simpler • Same as the rest of our parser Grammar for Expressions Needs to account for operator associativity • Also known as fixity • Determines how you apply operators of the same precedence • Operators can be left-associative or right-associative Needs to account for operator precedence • Precedence is a concept that you know from mathematics • Think PEMDAS • Apply higher precedence operators first Associativity By convention 7 + 3 + 1 is equivalent to (7 + 3) + 1, 7 - 3 - 1 is equivalent to (7 - 3) – 1, and 12 / 3 * 4 is equivalent to (12 / 3) * 4 • If we treated 7 - 3 - 1 as 7 - (3 - 1) the result would be 5 instead of the 3. • Another way to state this convention is associativity Associativity Addition, subtraction, multiplication, and division are left-associative - What does this mean? You have: 1 - 2 - 3 - 3 • operators (+, -, *, /, etc.) and • operands (numbers, ids, etc.) 1 2 • Left-associativity: if an operand has operators -
The Order of Operations Agreement Page 1
Lecture Notes The Order of Operations Agreement page 1 The order of operations rule is an agreement among mathematicians, it simplies notation. P stands for parentheses, E for exponents, M and D for multiplication and division, A and S for addition and subtraction. Notice that M and D are written next to each other. This is to suggest that multiplication and division are equally strong. Similarly, A and S are positioned to suggest that addition and subtraction are equally strong. This is the hierarchy, and there are two basic rules. 1. Between two operations that are on different levels of the hierarchy, we start with the operation that is higher. For example, between a division and a subtraction, we start with the division since it is higher in the hierarchy than subtraction. 2. Between two operations that are on the same level of the hierarchy, we start with the operation that comes rst from reading left to right. Example 1. Perform the indicated operations. 20 3 4 Solution: We observe two operations, a subtraction and a multiplication. Multiplication is higher in the hierarchy than subtraction, so we start there. 20 3 4 = multiplication 20 12 = subtraction = 8 Example 2. Perform the indicated operations. 36 3 2 Solution: It is a common mistake to start with the multiplication. The letters M and D are in the same line because they are equally strong; among them we proceed left to right. From left to right, the division comes rst. 36 3 2 = division 12 2 = multiplication = 24 Example 2v. Perform the indicated operations. -
