I am having some unusual compiler warning messages and my input is being skipped over...

[Zero Cool]

This program computes a patient's bill for a hospital stay...It is about complete except that I am getting a different compiler message.. it says that:

-first argument of 'int main(float, float, float)' should be 'int' [-Wmain],
-second argument of 'int main(float, float, float)' should be 'char **' [-Wmain],
-third argument of 'int main(float, float, float)' should probably be 'char **' [-Wmain]

Despite this it still runs however when it gets to the surgery type/cost input it skips over the input for the name of the surgery, and asks for input to surgery cost. Why is this and what do the compile warning messages me, because they obviously should be float... right?

Standard defines what the main() can take as parameters. Three floats is not an option.

[Zero Cool]

Is this why input is skipped over? How would I fix this?

[Zero Cool]

Well, I updated the main() parameters and declared the variables inside main instead. The program still skips over input. Why is this?

Hey man don't double post. I just answered your question in your other thread:

You're response did not help.
Adding
cin.ignore(std::numeric_limits<std::streamsize>::max()); results in an endless loop of input.
