Object Oriented Programming - Functions
1. Choose the correct statements regarding inline functions.

3. A function abc is defined as
void abc(int x=0, int y, int z=0)
{
cout << x << y << z;
}
Which of the following function calls is/are illegal? (Assume h, g are declared as integers)
- Option : D
- Explanation : Since the second argument is mandatory, any call should have at least the first two parameters. Some compilers expect the optional parameters to follow the others. Such compilers give a compilation error.

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.
