We can also define the default parameters in the function definition itself. The program below is equivalent to the one above. #include<iostream>usingnamespacestd;// defining the default argumentsvoiddisplay(charc ='*',intcount =3){for(inti =1; i <= count; ++i) {cout<< c; }cout<<e...
Parameters and Arguments The termparameteris used to describe the names for values that are expected to be supplied. The termargumentis used for the values provided for each parameter. Parameters can be specified in tuple or curried form, or in some combination of the two. You can pass argum...
There are several advantages of using Named arguments and Optional parameters. Named arguments are useful when we have methods with multiple optional parameters. They allow us to specify only those arguments that we need and ignore the rest. Furthermore, with named arguments, we improve the code ...
Fourth call introduces named parameter. Notice how we are giving value to first and third argument. Syntax is very simple:parameter:value. Use carefully Optional arguments are widely used in VBA for long time. Although they make life a little bit easier for programmers (you don’t have to re...
static void Main(string[] args) { Add(z: 8, x:5, y:10, c: 6, a:2.0, b:3.0); } As long as you name the arguments, you can pass them in any order and the compiler will not flag any error — i.e., this is perfectly valid in C#. Use optional parameters in C# Optional ...
Since java8 there's -parameters flag that retains param names for reflection (java.lang.reflect.Parameter#getName) Any plans to support it in constructor resolution logic? 10x

The difference is that in this suggestion you will get an error message, and in the other issue you won't get an error. Using named arguments on a function typed any should be illegal in my opinion, since the compiler doesn't know the index of the argument with that name. Contributor ...
