Question - C# / C Sharp

a. The value of x will be:
x = (2%2) + (2*2) - (2/2)
= 0 + 4 - 1
= 3
b. The value of x in this case will be:
x = ((2%2) + 2)*2 - (2/2)
= (0+2)*2 - (2/2)
= 4-1
= 3.

Though the values of x in the above cases are same, there is a difference in
the order/precedence in which the expressions are evaluated. Try with
different numbers like
1%2+3*4-5/2 and (1%2+3)*4 - 5/2, where the values differ.
