How to get void insertnameoffunction() to match insertnameoffunction() in int main()

[Smarta]

The two lines are:

void success(const void *sum1, const void *sum2, const void *sum3, const void *sum4, const void *sum5)

and in int main():
success(sum1, sum2, sum3, sum4, sum5)

What do I need to change in the int main() portion to get them to match? Currently it brings up an error saying that
all the sums are undeclared (first use in this function) in the success(sum1, sum2, sum3, sum4, sum5) line, but doesn't show the void line to be incorrect.

First, there are no variables in main you can use to make the function call to success.

Second, the success function arguments are const pointers to void. Why do that? void means no type. A void pointer can't be used until it is converted to a type so the success function must already know, somehow, what the type is. And if that is true, why not just use the type?

Third, even though the void line shows no errors, after you define variables in main, you will start to get errors because of my second point above.

When you call success() from within main, where do you expect the sum1 to sum5 variables to come from? That is, how and where are they defined?
