  • C++ Programming: Program Design Including Data Structures, Fifth Edition
    C++ Programming: From Problem Analysis to Program Design, Fifth Edition Chapter 5: Control Structures II (Repetition) Objectives In this chapter, you will: • Learn about repetition (looping) control structures • Explore how to construct and use count- controlled, sentinel-controlled, flag- controlled, and EOF-controlled repetition structures • Examine break and continue statements • Discover how to form and use nested control structures C++ Programming: From Problem Analysis to Program Design, Fifth Edition 2 Objectives (cont'd.) • Learn how to avoid bugs by avoiding patches • Learn how to debug loops C++ Programming: From Problem Analysis to Program Design, Fifth Edition 3 Why Is Repetition Needed? • Repetition allows you to efficiently use variables • Can input, add, and average multiple numbers using a limited number of variables • For example, to add five numbers: – Declare a variable for each number, input the numbers and add the variables together – Create a loop that reads a number into a variable and adds it to a variable that contains the sum of the numbers C++ Programming: From Problem Analysis to Program Design, Fifth Edition 4 while Looping (Repetition) Structure • The general form of the while statement is: while is a reserved word • Statement can be simple or compound • Expression acts as a decision maker and is usually a logical expression • Statement is called the body of the loop • The parentheses are part of the syntax C++ Programming: From Problem Analysis to Program Design, Fifth Edition 5 while Looping (Repetition)

  • 1 More on Type Checking Type Checking Done at Compile Time Is
    More on Type Checking Type Checking done at compile time is said to be static type checking. Type Checking done at run time is said to be dynamic type checking. Dynamic type checking is usually performed immediately before the execution of a particular operation. Dynamic type checking is usually implemented by storing a type tag in each data object that indicates the data type of the object. Dynamic type checking languages include SNOBOL4, LISP, APL, PERL, Visual BASIC, Ruby, and Python. Dynamic type checking is more often used in interpreted languages, whereas static type checking is used in compiled languages. Static type checking languages include C, Java, ML, FORTRAN, PL/I and Haskell. Static and Dynamic Type Checking The choice between static and dynamic typing requires some trade-offs. Many programmers strongly favor one over the other; some to the point of considering languages following the disfavored system to be unusable or crippled. Static typing finds type errors reliably and at compile time. This should increase the reliability of delivered program. However, programmers disagree over how common type errors are, and thus what proportion of those bugs which are written would be caught by static typing. Static typing advocates believe programs are more reliable when they have been type-checked, while dynamic typing advocates point to distributed code that has proven reliable and to small bug databases. The value of static typing, then, presumably increases as the strength of the type system is inc reased. Advocates of languages such as ML and Haskell have suggested that almost all bugs can be considered type errors, if the types used in a program are sufficiently well declared by the programmer or inferred by the compiler.

  • Scala Tutorial
    Scala Tutorial SCALA TUTORIAL Simply Easy Learning by tutorialspoint.com tutorialspoint.com i ABOUT THE TUTORIAL Scala Tutorial Scala is a modern multi-paradigm programming language designed to express common programming patterns in a concise, elegant, and type-safe way. Scala has been created by Martin Odersky and he released the first version in 2003. Scala smoothly integrates features of object-oriented and functional languages. This tutorial gives a great understanding on Scala. Audience This tutorial has been prepared for the beginners to help them understand programming Language Scala in simple and easy steps. After completing this tutorial, you will find yourself at a moderate level of expertise in using Scala from where you can take yourself to next levels. Prerequisites Scala Programming is based on Java, so if you are aware of Java syntax, then it's pretty easy to learn Scala. Further if you do not have expertise in Java but you know any other programming language like C, C++ or Python, then it will also help in grasping Scala concepts very quickly.

    Concepts in Programming Languages Supervision 1 { 18/19 v1 Supervisor: Joe Isaacs (josi2). All work should be submitted in PDF form 24 hours before the supervision to the email [email protected], ideally written in LATEX. If you have any questions on the course please include these at the top of the supervision work and we can talk about them in the supervision. Note: there is a revision guide http://www.cl.cam.ac.uk/teaching/1718/ConceptsPL/RG. pdf for this course. 1. What is the different between a static and dynamic typing. Give with justification which languages and static or dynamic. 2. What is the different between strong and weak typing. 3. What is type safety. How are type safety and type soundness distinct? 4. What type system does LISP have what are the basic types?, where have you seen a similar type system before. 5. What is a abstract machine, why are they useful? Where have you seen or used them before? 6. Name at least six different function calling schemes and which languages use each of them. 7. Give an overview of block-structured languages, include which ideas were first introduced in a programming language and how they influenced each other. Making sure to list the main characteristics of each language. You should talk about three distinct languages, then for each language make sure to make distinctions between different version of each language. Make a timeline using pen and paper or a diagram tool. 8. Using the type inference algorithm given in the notes (a typing checker with constraints) find the most general type for fn x ) fn y ) y x 9.
