Previous sections have shown how variables and constants can be manipulated using standard mathematical operators, such as +, −, *, and /. There are, however, a number of shorthand variations that can be written to abbreviate specific expressions. Consider the operators in the following table.
Given the integer variable Num, the shorthand expressions below can be seen to mean the following:
|Num += 5||Means:||Num = Num + 5|
|Num −= 5||Means:||Num = Num −5|
|Num++||Means:||Num = Num + 1|
|Num − −||Means:||Num = Num −1|
