C++: Introduction for non-C Programmers (5 day)

Show more Languages: C++ Training Courses

About this class

C++ is undoubtedly the most widely-used programming language for implementing object-oriented systems. The C++ language is based on the popular C language. However, the demand for the language has expanded beyond C programmers looking to upgrade to C++, and a number of C programming practices and features are not required, or are seen as detrimental, in C++ programs.

The C++ for Programmers course provides thorough practical and theoretical coverage of the C++ language for the experienced application programmer who has little or no recent C experience. It helps eliminate misconceptions and poor programming practices that can cause so many problems, by focusing on features of the language and standard library that enforce good practice and encourage clear and robust code.

Delegates with extensive C experience should attend the C++ for C Programmers course instead.

Who will the lesson benefit?

Developers with solid programming experience but little or no recent C.

What delegates will learn

• understand the key concepts and vocabulary of object orientation
• use fundamental and composite data types
• define and use classes
• write class member functions
• use pointers and dynamic memory
• use constructors and destructors
• write code that is efficient and robust
• build new classes from other classes using aggregation and association
• build new classes from other classes using inheritance
• use container classes, including template classes
• use operator overloading
• design and write code with polymorphic behaviour

What prerequisites are required

• Delegates must have solid experience of another modern high-level language, including writing and using functions/procedures/subroutines
• structured data types such as arrays, structs or records
• an understanding of scoped variables (i.e. local vs. global data).
