If function t is called what is printed void r(int x ,int y, int &z)
{
cout <<"r:x="<<x<<"y=",,y
<<"z=",,z,,endl;
x=x+1;//has no meaning since x is local to fn
z=y+x;//has no meaning since z is local to fn

}
void t()
{
int a,b,x;
a=20;
b=25;
x=250;
r(a,b,x);
r(x,a,b);
cout<<"t:a"<<a<<"b="<<b
<<"x="<<x<<endl;
}

result will be

20 25 250

250 20 25

20 25 250
