In this example, the ModifyValue method takes an int parameter by reference using the ref keyword. When you call this method in the Main method, you're passing the number variable by reference. As a result, the value of a number is modified within the ModifyValue method, and the change ...

()by value,which you might think would cause the string to be copied, but this is where the magic happens. Whenthe compiler sees a temporary being used to copy-construct an object, the compiler will simply use the same storage for both the temporary and the new object,so that copying ...
