Introduction to C++ 20 Programming Essentials

At Course Completion

This “skills-centric” course is about 50% hands-on lab and 50% lecture, designed to train attendees in basic coding with C++, coupling the most current, effective techniques with the soundest industry practices. Our engaging instructors and mentors are highly experienced practitioners who bring years of current "on-the-job" experience into every classroom.

Working in a hands-on learning environment, guided by our expert team, attendees will learn:

· Defining a class in C++

· Using private, public and protected keywords to control access to class members

· Writing constructors and destructors

· Writing classes with const and static class members

· Overloading operators

· Implementing polymorphic methods in programs

· Writing programs using file I/O and string streams

· Using manipulators and stream flags to format output

· Using the keyword template to write generic functions and classes

· Writing programs that use generic classes and functions

· Writing programs that use algorithms and containers of the Standard Library

· Apply object-oriented design techniques to real-world programming problems

· Using algorithms and containers of the Standard Library to manipulate string data

· Using try() blocks to trap exceptions

· Using catch() blocks to handle exceptions

· Defining exceptions and using throw to trigger them
