Default arguments are the arguments that are passed in the function definition which is used by the compiler if no arguments are provided, at the time of function call.Default Argument ValueTo define the default value to an argument, you can assign the value by using the equals sign (=)....

Default arguments don’t work for functions called through function pointers Isn’t this topic better placed in https://www.learncpp.com/cpp-tutorial/function-pointers/ ? Because no one knows what a pointer is yet, so people will skip this anyway, and by the time they know pointers, they ...
In C++, you can provide the default values /arguments to the data members by using the default arguments while defining the constructor of the class.
Yes, we cover this in the next lesson: https://www.learncpp.com/cpp-tutorial/delegating-constructors-and-default-arguments/ 0 Reply Abdel September 15, 2023 6:53 am class Implicit { public: int a; // note: no default initialization value int b {}; // implicit default constructor ...
In C++ programming, we can provide default values for function parameters. If a function with default arguments is called without passing arguments, then the default parameters are used. However, if arguments are passed while calling the function, the default arguments are ignored. Working of defaul...
