Cleaning up my code.....

Hey everyone. THis is a finished version of Craps, but I have a tiny favor to ask. Right after the main game loop is finished, I display a frequency table of the rolls that were, well, rolled. It''s a bunch of if statments determining the formatting of the percentages. How the heck would I decrease the size of this / put it in a function somehow? Thanks //---------------------------------------------------------------------------- // driver.cpp // This program simulates the street version of Craps. The player starts // the game with $100 in their pot. They are allowed to bet, but they can''t // bet less than $2 or more than their pot amount. Here are the rules to // the game: Each roll is started by rolling 2 six-sided dice. If the throw // total on the first roll is 7 or 11, the player wins. If the throw total // on the first roll is 2, 3, or 12, the player loses. Any other throw total // becomes the player''s ''point.'' The player must roll the ''point'' in order // to win, but if they get a 7 before that, the player loses. // // Project: Craps //---------------------------------------------------------------------------- // I/O #include <iostream> // Reading/writing files #include <fstream> // Needed for rand and srand #include <cstdlib> // Needed for time #include <ctime> // Needed for clearing the screen #include <stdlib.h> using namespace std;

yeah...looks good.. just one thing... change NUM_COMBOS to arSize inside the functoin....eg

  void FrequencyTable( const int arr[], int arSize, int r ){	cout << "Frequency:" << endl;	for ( int i = 0; i < arSize; i++ )	{		float p = float ( arr[i] * 100 ) / r;		if ( p != 0 )		{			cout.setf( ios_base :: fixed );			cout.precision( 2 );		}		cout << i  + OFF_SET  << "   " << p << "%" << endl;		cout.unsetf( ios_base :: fixed );	}}
