Program is running above input ^ z (Ctrl z) end of the cycle 0
But at the same time enter 123 ^ z (Ctrl z) cycle cannot end is why? The small white consult

Run no problem:

 # include 


//the above program run time input ^ z (Ctrl z) end of the cycle 0 
//but at the same time enter 123 ^ z (Ctrl z) cycle cannot end is why? 


Int main (int arg c, char * const argv) 
{
int a; 
Int b=0; 
While (the scanf (" % d ", & amp; A)! EOF)={
B++; 
Printf (" % d \ n ", b); 
} 
Printf (" % d ", b); 

return 0; 
}
