The "+ +" and "-" operators in the Go language

This is a created article in which the information may have evolved or changed.

The following excerpt from the Go programming Language:

The increment statement i++ adds 1 to I; It ' s equivalent to i + = 1 which are in turn equivalent to i = i + 1. There ' s a corresponding decrement statement i–that subtracts 1. These was statements, not expressions as the Y was in the very languages in the C family, so j = i++ was illegal, and the Y are Postfix only, so–i are not legal either.

Note that, i++ and i-- in the Go language is a statement, not an expression, so you cannot assign a value to another variable. Furthermore there is no ++i and --i .
