CPP for Intermediates

This page will have CPP resources broken up by topic and will be most helpful to those who already have a good understanding of Java or OOP in general.

Topics

Primitives

primitives in C++ are very similar to those in Java with some minor differences.

• boolean is changed to bool
• long is a modifier on int so long int would be long in java. They can be chained however so you can have long long int for a datatype even bigger than Java's
• strings are not considered a primitive. you'll need to #include <string> to get access to std::string which operates similarly to Java's string.

Classes and Structs

for an examples go to W3Schools

• Structs work the same as Classes, just replace class with struct
• observe the semicolon at the end of the last }

The main difference between Classes and Structs is that Classes have private attribute visibility by default while Structs have public attribute visibility by default.

• in practice we use classes like in Java, while we use structs as data classes.

Classes in our code base are separated into 2 files a *.cpp file and a .h file. h files are header files which contain declaration details while the cpp files contain the implementation.

Learning:

if you'd like a course designed to bring programmers up to scope in CPP then Codecademy has a course for CPP designed for people who already have knowledge in programming.
