There are quite a lot of rules in the C++ Core Guidelines dealing with expressions and statements. To be precise, there are more than 50 rules are about declarations, expressions, statements, and arithmetic expressions.
Passing smart pointers is an important topic which is seldom addressed. This ends with the C++ core guidelines because they have six rules for passing std::shared_ptr and std::unique_ptr.
There were a lot of C++ experts who said that smart pointers were the most important feature of C++11. Today, I will write about smart pointers in C++.
The guidelines has six rules for explicit memory allocation and deallocation. Six! Maybe you are surprised because there is a simple rule in modern C++: don't use new and delete. Obviously, the story is not so simple.
I have prepared the pdf bundle. To get it is quite simple.
This and the next posts will probably be about the most important concern in programming: resource management. The C++ Core Guidelines has rules for resource management in general but also rules for allocation and deallocation and smart pointers in particular. Today I will begin with the general rules of resource management.
The section to enumerations has eight rules. Since C++11, we have scoped enumerations which overcome a lot of the drawbacks of classical enumerations.
Now, it's time to choose the next pdf bundle? You will get all posts, all source files, and a cmake file to the chosen topic.
A union is a special data type where all members start at the same address. A union can hold only one type at a time; therefore, you can save memory. A tagged union is a union which keeps track of its types.
