Functions Q.5

a=chg(b) ;

cout << a << b ;

If the function chg is coded as

int chg(int x)
{
x = 10;

return ();

}
then

Option : C
Explanation : Here the default parameter passing mechanism of pass by value will be used. Any change done to the parameter will not be reflected outside the function. So, b retains its value 2.

I agree with the Terms.
