Thread: Sorting a set of numbers based on what the user inputs?

I've looked around for some help on this but I can only find how to sort for a specific array size. The directions are as follows:

Write a program that finds the largest in a series of numbers entered by the user. The program must prompt the user to enter numbers one by one. When the user enters a 0 or a negative number, the program must display the largest nonnegative number entered.

Here is what I have so far:

Code:

int main(int argc, char *argv[])
{
  /*This program will find the largest number in a series of positive numbers */
  /*entered one number at a time. Enter a 0 or negative number to end the loop*/

  int n, temp;
  int counter = 1;
  int largest = 0;
  printf("Enter a number:");
  scanf("%d", &n);
  while(n > 0)
  {
          printf("Enter a number:");
          scanf("%d", &n);
  }
  while(n <= 0)
  {
          while(counter <= n)
          {
          if(n > largest)
          {
               temp = 0;
               temp = largest;
               largest = n;
          }
          else if(n < largest);
          {
                 temp = 0;
                 temp = largest;
                 largest = largest;
          }
          
          counter++;
  
          
          printf("The largerst number is: %d", &largest);
}
}
  system("PAUSE");	
  return 0;
 }

I am using bloodshed if that makes any difference, please let me know what I need to change, thanks.
