A default Parameter is a value that is assigned to each parameter while declaring a function.
This value is used if that parameter is left blank while calling the function. To specify a default value for a particular parameter, we simply assign a value to the parameter in the function declaration.
If the value is not passed for this parameter during the function call, then the compiler uses the default value provided. If a value is specified, then this default value is stepped on and the passed value is used.
