Problem with bubble sort

[bluetickk]

The sorting method works, I have used it without strcmp() for files of characters, but the file im sorting is array of chars, so I must use strcmp() and strcpy(), my only issue is that it sorts the files in reverse alphabetical order. Please shed some light on this if you can help.

// sorts the cities in alphabetical order
void sortArrays( cityInfo cities[], int numCities )
{
	char tempCityName[25];
	int tempLowTemp, tempHighTemp;
	bool swapped = true;
	int a = 0;

	while(swapped)
	{
		swapped = false;
		a++;

		for(int i=0; i < numCities - a; i++)
		{
			if( strcmp( cities[i].cityName, cities[i+1].cityName ) < 0) // checks if first city is alphabetically lower than second city
			{
				strcpy( tempCityName, cities[i].cityName );
				strcpy( cities[i].cityName, cities[i+1].cityName );
				strcpy( cities[i+1].cityName, tempCityName ); // swaps cities in the array

				tempLowTemp = cities[i].lowTemp;
				cities[i].lowTemp = cities[i+1].lowTemp;
				cities[i+1].lowTemp = tempLowTemp; // swaps low temp in array

				tempHighTemp = cities[i].highTemp;
				cities[i].highTemp = cities[i+1].highTemp;
				cities[i+1].highTemp = tempHighTemp; // swaps high temp in array

				swapped = true;
			}
		}
	}
}

wow duh, I just swapped the argument in the if statement to be greater than 0 and it solved my issue.
