 | What's the difference between = and == Where are you using one, where you should be using the other?  |

| | You're using a switch/case as an array subscript. Consider something like [code] char *suits[] = { "Hearts", "Clubs", "Diamonds", "Spades" }; char *ranks[] = { "Ace", "Deuce", "Three", // you get the idea } suit = rand()%4; ranCards = rand()%13; cout << ranks[ranCards] << " (of " << suits[suit] << …  |
| | 1. main returns int, not void 2. Avoid single letter identifiers (with the exception of i,j as being ubiquitous loop variables). For example, o and 0 make for very unreadable code. |
| | Neither do we, until you tell us which OS and Compiler you're using. |

| | Is this the small "doesn't work" because it no longer sorts? Or a larger "DOESN'T WORK" because the program crashes with some bizarre error message? I see a lot of scope for blowing the stack with the large number of large arrays on the stack. Does 32001 BY ITSELF work? … |

| | Personally, I would just do [ICODE]awk '{print $2 / 1000000 }'[/ICODE] and stop worrying about just how good the maths is in the shell. Also, awk has printf() as well, so you've got really good control over the format as well. |
