Thread: Print Maximum number

Hey guys-

I'm having an issue with this program I wrote. It is supposed to have a user enter values and then output the maximum value of those values entered, using very basic C Programming. If only the sentinel value is entered, it will print out an error message. I have that working properly, but when I enter values, it outputs the maxmium, but when I enter the sentinel value (999), it outputs that as the maximum, which it shouldn't do. Any ideas? I'm probably just overlooking something very simple. I appreciate the help! Thanks!!

-----------------

Code:

...
while (temp != 999)
{               
   printf("Enter another value [enter 999 to stop]:\n");
   scanf("%f",&temp);
   counter == counter++; 

	if ( temp > max) 
	{
	max = temp;
	}
	else if ( temp < max)
	{
	temp = temp;
	}
}

if ( counter != 1 )
   {
   printf("The maximum is: %f\n", max);
   }
else
   {
   printf("No valid entires:\n");
   }
}
