2023年9月11日 · 26.1 — Template classes. Alex September 11, 2023. In a previous chapter, we covered function templates ( 11.6 -- Function templates ), which allow us to generalize functions to work with many different data types. While this is a great start down the road to generalized programming, it doesn’t solve all of our problems.
2024年3月30日 · 14.2 — Introduction to classes. In the previous chapter, we covered structs ( 13.7 -- Introduction to structs, members, and member selection ), and discussed how they are great for bundling multiple member variables into a single object that can be initialized and passed around as a unit. In other words, structs provide a convenient package ...
2023年9月11日 · 23.1 — Object relationships. Life is full of recurring patterns, relationships, and hierarchies between objects. By exploring and understanding these, we can gain insight into how real-life objects behave, enhancing our understanding of those objects. For example, let’s say one day you’re walking down the street, and you see a bright ...
2023年9月11日 · 26.x — Chapter 26 summary and quiz. Alex September 11, 2023. Templates allow us to write functions or classes using placeholder types, so that we can stencil out identical versions of the function or class using different types. A function or class that has been instantiated is called a function or class instance.
2024年3月25日 · That said, it’s not uncommon for programmers to use default initialization instead of value initialization for class types. This is partly for historic reasons (as value initialization wasn’t introduced until C++11), and partly because there is a similar case (for non-aggregates) where default initialization can be more efficient (we cover this case in 14.9 -- Introduction to constructors ).
2023年12月15日 · 14.15 — Class initialization and copy elision. Way back in lesson 1.4 -- Variable assignment and initialization, we discuss 6 basic types of initialization for objects with fundamental types: All of these initialization types are valid for object with class types: std :: cout << "Foo() "; } // Normal constructor Foo(int x) {.
2024年4月16日 · In general programming, an aggregate data type (also called an aggregate) is any type that can contain multiple data members. In C++, arrays and structs with only data members are aggregates. Aggregates use a form of initialization called aggregate initialization, which allows us to directly initialize the members of aggregates.
