Division ( / )
The division operator (/) perform arithmetic division on numbers (literals or variables).
The decrement operator (--) decrements numbers by one.If used as a postfix to n, the operator returns the current n and then assigns the decremented the value.If used as a prefix to n, the operator assigns the decremented n and then returns the changed value.
In this case, b is set to the initial value of a. So, b will be 5, and c will be 4
In this case, b is set to the new value of a. So, b will be 4, and c will be 4.
