In the following example, we have to use getCents() to convert our Cents variable back into an integer so we can print it using printInt(): If we have already written a lot of functions that take integers as parameters, our code will be littered with calls to getCents(), which makes it more messy than it needs to be.

This will allow us to cast our Cents class directly into an int. g H DRR, Liyue Shen resnet-50, , 409644tensor,transformtensor2048244, CT.

S_L, n WebExamples. The following example shows how this is done: Now in our example, we can call printInt() like this: The compiler will first note that function printInt takes an integer parameter. This allows you to do something like this: Consequently, this program will print the value: which makes sense, since 9 dollars is 900 cents!
