int main(){
   int x=0 , y=0 ;

   if (++x == 1 || y++ ==1)
     cout << "(1)" << x << ',' << y << end1;
   if (++x == 1 || y++ ==1)
     cout << "(2)" << x << ',' << y << end1;
   return 0;
}


2.what is th output of the following c++ program?

int main(){
   char x='A';

   switch (x++) {
   case 'A':
      cout << "x=A" ;
   case 'B':
      cout << "x=B" ;
   case 'C':
      cout << "x=C" ;
   }
   return 0;
}



3.which element of array A is changed after invoking modifyArray()? what does
  the Array A become after modifyArray() returns to the main program?

modifyArray(int b[] , size){
   b = &b[3] ;
   b[3] = 0 ;
}

int main (void) {
   int A[] = {1,2,3,4,5,6,7,8,9};
   modifyArray(A,9);
   return 0 ;
}



感謝各位的幫助<(_ _)>
