I can't understand why a=18 for 3*=6? Please clarify me.

Why the answer is not 12 and 14?

Because first prefer default arguments and if not match then go for others.

case "cout<<data.Addition(1)<<" ";"

Here the function will carry "Addition(1,10)"
And the evaluation will be
1*=10+2;
=>1*=12
And hence a=12.

case cout<<data.Addition(3,4);

Here the function will carry "Addition(3,4)"
And the evaluation will be
3*=4+2;
=>3*=6;
And hence a=18.
