For better understanding of arguments and return values in functions, user-defined functions can be in various forms like: Function with no argument and no return value Function with no argument but return value

A user-defined function is stored in a variable or macro and expects one or more parameters to be passed by the caller. User-Defined Functions Storing command sequences in variables opens the door to a wide range of applica- tions. For instance, here's a nice little macro to kill a ...
User-defined conversion function is invoked in the second stage of theimplicit conversion, which consists of zero or oneconverting constructoror zero or one user-defined conversion function. If both conversion functions and converting constructors can be used to perform some user-defined conversion, ...
C++ STL 2D Vector: Here, we are going to learn about the vector of vector or 2D vector in C++ STL, its declaration with user defined size.

user-defined-string-literal - the character sequence "" followed, without a space, by the character sequence that becomes the ud-suffix. This special syntax makes it possible to use language keywords and reserved identifiers as ud-suffixes, and is used by the declaration of operator ""if from...
Functions aren’t considered user-defined types (even though they require a name and a definition before they can be used) because it is the function itself being given a name and a definition, not the function’s type. Functions that we define ourselves are called user-defined functions inst...
All the data types in C++ can be classified into 4 categories (or types): primitive/ built-in types, derived data types, user-defined types, and abstract data types. In this article, we will discuss the categories of data types in Cpp in detail, as well as their subtypes, with the he...
