Functions Q.7

7int a =1 , b=2;

a=chg(b) ;

cout << a << b ;

If the function chg is coded as

int chg(const int &x)

{

x=10;

return ()

};

Option : A
Explanation : Here the function chg tries to change the parameter x, which is not allowed as it is declared to be a constant integer. So, the compiler gives an error.
