C++ for C Programmers

Displaying courses for Great Britain [Change]

Overview

C++ is undoubtedly one of the most popular programming languages for software development. It brings language enhancements and object-oriented programming support to C++. However, C++ is a large and sometimes difficult language, and even with a C background, a programmer needs to understand C++ programming style as well as C++constructs to get the best out of it. QA Training's highly successful C++ for C Programmers course has a thorough theoretical and practical coverage of the language. This helps to eliminate the misconceptions and poor programming practice that can cause so many problems.

This is a hands on course with a mix of tuition and practical sessions for each technical chapter which reinforce the C++ syntax and object-oriented programming techniques covered in the course.

Objectives

At the end of this course you will be able to:

  • Define classes.
  • Write class member functions.
  • Use constructors, destructors and dynamic memory.
  • Write code that is efficient and robust.
  • Build new classes from other classes using inheritance, composition and association.
  • Use template classes.
  • Use operator overloading.
  • Design and write classes with polymorphic behaviour.

Audience

For experienced C programmers, the course will illustrate how to get the benefits of good software engineering and code reuse by using standard C++ and object-oriented programming techniques in real-world programming situations. There will be ample opportunity to apply these techniques during the practical sessions.

C Programmers wishing to learn or improve in C++.

Prerequisites

  • Delegates must have solid experience of C including structures (i.e. struct and/or class); Declaration and use of pointers; Function declaration, definition and use with call by value or call by pointer; Dynamic memory allocation (i.e. malloc and free, or new and delete); Multiple source file projects (requiring project files or makes files). You should also have a good appreciation of object-oriented principles or have attended our Object-Oriented Primer course.
  • Delegates with less than four months or no recent experience of C should attend the C++ for non-C Programmers course instead
