Hi,
I've been searching around the internet for an answer to my problem for a little bit now but haven't been able to find anything. This being my first big C++ project I've been running in to lots of trouble, most notably with the inability to take input from a cin statement the second time I call one of my functions. The first time through the function everything works as it should but the second time through the cout text is output put cin acts as if the user has already typed in something (although when using my VS 2003 .net debugger I can see that the values remain at 0). Any help would be greatly appreciated.
The file in question contains 3 functions so I'll truncated it down to the one I'm having problems with. The problems are occurring directly at the begining of the file with the cin statements but I included the whole thing just to make sure although I'm doubting there's anything wrong (at least with regards to the cin statements) at the end of the file.
Thanks for any help anyone can bestow upon me.
Remember I'm able to compile the code and run it once just fine, just those first cins asking for team, unit, and position are giving me problems. Mucho frustrating.PHP Code:#include <iostream>
#include <stdio.h>
#include <stdlib.h>

// understand what's going on half of the time.

variables equal to numbers that can be used for settings in an array.*/

tokenTwo = strtok(NULL, delimiters);
if(*tokenOne <= 85) // converts to array equivilent of the ASCII letter (IE A converted to 0 for position 1)
CreateY = *tokenOne - 65;
else
CreateY = *tokenOne - 97;
/* I use strtod here to take out the int from tokentwo. Using strtod on the
pointer allows us to remove the actual number and place it into an int. Other-
wise you would be stuck just trying to use the first digit of the number since
strtok sets each char in the string to one digit, so if tokentwo took in '10'
you would only have access to the number '1' since the '1' and the '0' are in
their own section of memory of the array. These can be printed with %s, but
you can't actually use the value itself. */

***edit***
I forgot to mention... all I recieve as output the second time through the function is a constant barrage of error messages. The "error testing" picks up a bad input somewhere and because cin isn't working the cycle repeats ad infinatum until I close my program. Oh... and I'm compiling in Visual Studio 2003 .net
