Returning More Values by Reference 217

int & large (int & p, int & q);

int main()

{ clrscr();

int l,k;

cout<<“\n Enter values of l and k: ”;

cin>>l>>k;

large (l,k)=120;

cout<<“ l= ”<<l << “ k=”<<k;

return 0;

}

int & large (int & p, int & q)

{

if (p>q) return p;

else return q;

}

OUTPUT

Enter values of l and k : 4 8

l= 4 k=120

Enter values of l and k : 9 2

l= 120 k=2

Explanation: In function main(), the statement large (l, k) = 120 calls the function large().

It returns reference to the variable containing larger value and assigns the value 120 to it. The

return type of function large() is int ‘&’ (reference), it indicates that the call to function ...
