need help writing function

Nov 24th, 2007

how would i write a maximum number test function that will take any number of arguments and returns the greatest of them???

i know i need to used recursion function, but how should i declare the function??

here is what i have so far

 c++ Syntax (Toggle Plain Text) 
double maxNumber( double inputNum,A double inputNumB)
{  double finalNum;
   if inputNumA > inputNumB {
   finalNum == inputNumA
   return inputNumA;
}}
double maxNumber( double inputNum,A double inputNumB)
{  double finalNum;
   if inputNumA > inputNumB {
   finalNum == inputNumA
   return inputNumA;
}}

So what's wrong with say
- storing a variable number of values in a vector
- scanning that vector for the largest value, using a for loop

Put your doubles into a vector, let's say dvector, and then use something like *max_element(dvector.begin(), dvector.end())

I upped my sanitary measures, up yours!

OK, so go with plain good old fashioned arrays then, and start with a small program which fills the array with some numbers input by the user.

I think it would be very odd that your professor wants you to create a function that takes a variable number of arguments. Perhaps you should work with finding the largest number in an array?

Don't use recursion unless your professor explicitly asked you to. I don't imagine he did if you are to work with a variable number of numbers...

To figure out your problem, you have to think about how you, yourself can find the largest number in a list. For example, if I give you the following numbers, which is largest?
