C++ newbie i really need some help debugging a program

The program is meant to give you the amount of odd and even numbers between to positive integers and print out all of the Prime numbers and tell you how many prime numbers there are.

Code:

#include<iostream>
using namespace std;
int main()
{
int n;
int startNumber;
int endNumber;
int count;
int evenCounter= 0;
int oddCounter= 0;

cout << " Please enter your starting number followed by your ending number " << endl;
   cin>> startNumber;
   cin>> endNumber;
while (startNumber <= endNumber)//beginning of the condition
{
   if (startNumber  2==0)
   evenCounter++;

 else if (startNumber !=0)
{
 oddCounter++;
 startNumber++;
{
cout << "The prime numbers between " << startNumber << " and " << endNumber << " are: " << endl;
for (n = startNumber; n <= endNumber; n++){
    count = 0;
 for (int i = 2; i <= n/2; i++){
    if(ni==0){
    count++;
}
}
if(count==0 && n!=1)
{
    cout << n << endl;
}
    }
}
 //end of the condition

cout << "The number of odd number is " << oddCounter<< endl;
cout << "The number of even number is " << evenCounter<< endl;
}
}
return 0;
}

Before debugging, please fix every errors and warnings the compiler gives you. If you cannot do that, quote the complete message.

I second Nevemteve's suggestion as well as add that you should qualify some of the test criterion where you've found problems. Also if you're having difficulties compiling and running at all, then cut/paste that information and illustrate the parts where you are stuck.

Based on a quick look you have typo's in lines 17 and 29. Fix those.

Don't alter your input numbers if you need to retain those for output or reference later in your program, instead make copies of them for modification.
