a) To the rightmost side of the parameter list
b) To the leftmost side of the parameter list
c) Anywhere inside the parameter list
d) Middle of the parameter list
Answer: a
Explanation: Default parameters are defined to the rightmost side of parameter list in a function to differentiate between the normal and default parameters for example if a function is defined as fun(int x = 5, int y) then if we call fun(10) then 10 should be given to x or y because one can apply both logics like x = 10 already defined and 10 passed is for y but if compiler reads it from left to right it will think it is for x and no parameter is given for y, therefore, the compiler will give error.
