A pointer to a function must have the same type as the function. Attempts to take the address of a function by reference without specifying the type of the function will produce an error. The type of a function is not affected by arguments with default values. The following example shows t...
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...
If we call the function without an argument, it uses the default value ("Norway"): Example voidmyFunction(string country ="Norway") { cout<< country <<"\n"; } intmain() { myFunction("Sweden"); myFunction("India"); myFunction(); ...

In C++, default parameters allow function declarations to specify default values for parameters. However, redefining default parameters in function declarations or definitions causes the compiler to raise an error. This error occurs when a function’s default parameters are specified in both its declarat...
Default parameter values must be specified last in the function definition. Default parameters can be overridden by passing values during the function call. Default parameter values are optional when calling the function. All function parameters must have default values. ...
The following example shows using named parameters to call a method with default parameter values in Scala -Open Compiler object Demo { def calculateTotal(price: Double, tax: Double = 0.1, discount: Double = 0.05): Double = { price + (price * tax) - (price * discount) } def main(...
function functionName(param1 = default1, param2 = default2, ...) { // function body } A default value is set for the parameters in the function. While calling the function, if the arguments are specified then the function takes those values, but if no arguments are passed then the ...
This is a new language facility (not available in C) whose goal is a further improvement in code readability and modifiability. When declaring a function, you can specify default values for one or more parameters in the parameter list.
