Parenthesize and evaluate the following expressions in C++:

A)

a = b += c++ -d + --e/-f;

What does the expression evaluate to given int a=1, b=2, c=12, d=2, e=5, f=2?

B)

Assume we have: int i = 5, j = 10, k = 2, result;

What is the output of each of the following expression?

result = 2 * i % 5 * 4 + (j - 3) / (k + 2);
