C++ Algorithm Help?

I don't even know where to begin on this problem somebody please help me out. If you don't know please do not answer!

Write an algorithm to read a sequence of integers, ignoring all numbers that are less than 1. Count how many even and odd numbers there are, and print these counts. For example, with input 7 25 100 2 -6 1 0 3, the output should be
Even = 2, odd = 4
There were two even numbers (100 and 2), four odd numbers (7, 25, 1, and 3), and two numbers were ignored (-6 and 0). Your algorithm should work for any input, not just this example.

It's been a LONG time since I wrote any C++, so I can't / won't write your whole program for you.

You need an odd counter and an even counter variable. Decide how many numbers you will evaluate. That will be your FOR loop count. Initialize your counters.

to determine odd or even, use modulus. I forget what the mod operator is in c++. I also forget the syntax of the CIN and COUT etc... and you have to include iostream, or something like that...

int oddCount = 0;
int evenCount = 0;
int userInput = 0;

for(int i=0, 6, i++)
{
CIN>userInput;
if(userinput>0)
{
if(userInput%2 == 0)
evenCount++;
else
oddCount++
}
}

COUT yer variables.
