I am sorry that ,I forgot the code:"++index;" in the loop.

int curPlayer = 12;
TCHAR Rools[12];
int index = 0;
int temp;
TCHAR* q = Rools;
while(1)
{
   temp = 5;
   itoa( temp, q++, 10 );

1. You have an array with 12 elements which means that the highest index is 11 and you are deliberately accessing index 12, which is out of bounds. In C/C++ everything is zero-based so the first index is 0 and not 1.
2. You haven't accounted for the fact that itoa() adds a terminating zero to the target string after the conversion.

int curPlayer = 11;
TCHAR Rools[12]; // With space for 11 char + the terminating zero
int index = 0;
int temp = 5;
TCHAR* q = Rools;
for( index = 0; index < curPlayer; ++index )
{
   itoa( temp, q++, 10 );
}
