C++: Introduction for non-C Programmers (4 day)

Show more Development Training Courses

About this class

Object-oriented (OO) programming offers greater reliability, maintainability and reusability than older, structured programming methods. C++, a language derived from C, supports OO with a high degree of efficiency and portability. C++ is a well-established, mainstream language used across a broad range of applications.

This course provides a solid foundation in C++ for programmers without experience with the C language. You gain an understanding of key OO programming concepts and valuable hands-on experience developing C++ programs.

Who will the lesson benefit?

This course is for those interested in programming with C++. Professional programming experience other than C programming experience is assumed.

What delegates will learn

• Create, compile and run C++ programs
• Read and understand C++ syntax
• Write functions, decisions, loops and exceptions
• Declare, use and distinguish variables, constants, arrays, pointers and references
• Define and implement classes to produce reliable, reusable code
• Use STL classes and instantiate templates
• Implement object-oriented designs using encapsulation, inheritance and polymorphism
