Answer 2

Whenever you call x(var1, var2), var1 and var2 are passed as references to the function and their values are set to 3 and 4 respectively. Then the value of var1 is returned. I have no idea what statements like cout<<"while c=x(b,a)"<<endl; are supposed to do. There's no while loop involved in the code.
