C++ language

What is the output of the following code fragment? You may assume it is part of a complete, correct C++ program. Please use pencil and erase mistakes. You may not type. Assume the output starts at the left end of the top line below. Show your work (variable boxes, etc.). You will not get any points if you do not show your work for this. Do not use the output lines for your scratch work, they are for the output only.

int mystery( int &a, int b ) 

{ int c = a + b;

 a = c + a / b; 

b = a + c; cout << a << ' ' << b << ' ' << c << endl; return a + b + c; 

}

int main( void ) 

{ int a = 3, b = 4; int c = mystery( b, a ); cout << a << ' ' << b << ' ' << c << endl; a = mystery( b, c ); cout << a << ' ' << b << ' ' << c << endl; return 0;
