Infinite Recursion · Apr 10th, 2005, 10:59 PM

yeah..

while ( ; ; ) and for (EVER) are infinite loops... they have to have an exit condition. I defined EVER as ; ; because I thought it was cooler saying forever as opposed to the other stuff.

This way or the way you are mentioning in your post above would work... all that really matters is that you have the while loop playing a part somewhere... lol

good luck dude

oops... i don't think the ;; works with a while loop...
you can do this and still maintain the forever stuff...

#define FOREVER true

while (FOREVER)
{
GetNums();
}

(thats odd, thought you replied with the WHILE (;

stuff not working... your reply seems to have disappeared... at any rate, you can do the FOREVER as a boolean as I have it above to take care of that problem)

(Toggle Plain Text)

define EVER ;;

for (EVER)

lol...

Why the complexity? Instead of an array, have a single int variable (Like IR, but no function calls. No need for the pushes and calls). Every time you get input, if it the input is larger than the current variable, set the variable to the input. When you exit the loop, the variable will already be set to the max. It is both efficient in memory and speed. Excuse my syntax, and crappy exit condition (Is there a command to exit a loop?):

(Toggle Plain Text)

bool exiting = false;
int max = 0;
int input = 0;
while (!exiting) {
     cout << "Number, or -1 to exit: " << endl;
   cin >> input;
    
    if (input > max) { max = input; (need a semicolon?) }
    if (input == -1) {
         cout << "Max: " << max;
          exiting = true;
     }

}

return 0;

because someone like me looks at things too hard, and I try to analyze everything to the finest detail. You should watch me solve my brothers 3rd grade math problems....

ok that was a joke, but I seriously do analyze things very hard. I guess I just overestimate everything

Thanks Dameon for your advice

i was under the impression that it had to be relatively complex.... being a school assignment. but yes, admittingly so, I over-analyze everything as well. I'll spend days on a trivial problem sometimes. Anyhow, to exit the loop you could use break() or exit(0);
