Find out the final values of a,b and c where following expressions are executed sequentially:[4]int a = 2, b =3, c;a = (b++) + (++b) + a;c = a>b ? a:b;b = (a++) + (b--) + a;c = c++*b--;
What is the output of the following statements?
• bool b = 3;
cout << b;
• bool z = 2;
cout << z;
• int x = 12;
bool y = true;
cout << x + y;
Rewrite the following expressions using an if . . . else statement.
(Assume that all variables are declared properly.) (9)
a. (overSpeed > 10) ? fine = 200 : fine = 75;
