Try Catch Question

[pkfx]

I need to use try...catch so if the user enters more then 10 digits

#include <iostream>

int main( int argc, const char*argv )
{
	int numInput = 0, avgCount = 0, totalCount = 0;  
	float average = 0;

	while( numInput != 99 )
	{
		
		std::cout << "Enter a Number (Max 10 digits)(99 to Exit): ";
		std::cin >> numInput;

		if ( numInput != 99 )
		{
			totalCount += numInput;
			avgCount += 1;
		}
	}
	
	try
	{
		if( avgCount == 0 )
		{
			throw 0;
		}
		average = totalCount / avgCount;
	}
	catch(...)
	{
		std::cout << "Divide by Zero error" << std::endl;
		totalCount = 0;
	}
	
	std::cout << "Average of all Inputs: " << average << std::endl;

	system("pause");
	return 0;
}
