Consider the statements in (A) and (B) below: c++ code

(A) cin >> x;

if (x >=0)

x = x + 15;

else if (x >= 1)

x = x + 5;

(B) cin >> x;

if (x >=0)

x = x + 12;

if (x >= 1)

x = x + 6;

a) For the statement in (A) above, what is the final value of x if the input value is 0 ? Show your work by tracing the code. (2 marks)

b) For the statement in (B) above, what is the final value of x if the input value is 0 ? Show your work by tracing the code.
