If your class has const members, then default arguments can be provided in the constructor to make initialization easier. Syntax classBox{public:constintlength,width;Box(intl=5,intw=10):length(l),width(w){}}; This constructor uses default arguments (length = 5 and width = 10) to initiali...
Default arguments Allows a function to be called without providing one or more trailing arguments. Indicated by using the following syntax for a parameter in theparameter-listof afunction declaration. attr (optional)decl-specifier-seqdeclarator=initializer(1)...
C++ does not (as of C++23) support a function call syntax such asprint(,,3)(as a way to provide an explicit value forzwhile using the default arguments forxandy. This has three major consequences: In a function call, any explicitly provided arguments must be the leftmost arguments (argume...
Later languages (for example, in C++) allow the programmer to specify default arguments that always have a value, even if one is not specified when calling the function. For example, in the following function declaration: int MyFunc(int a, int b, int c=12); This function takes three ar...
