1.9. Augmented Assignments

An augmented assignment merges an assignment statement with an operator, resulting in a more concise statement. The execution of an augmented assignment involves the following steps:

1. Evaluate the expression on the right side of the = sign to yield a value.

2. Apply the operator associated with the = sign to the variable on the left of the = and the generated value. This produces another value. Store the memory address of this value in the variable on the left of the =.

Table Table 1.2 shows all the augmented assignments.

Table 1.2 Arithmetic operators

Symbol	Example	Result
+=	x = 7, x += 2	x refers to 9
-=	x = 7, x -= 2	x refers 5
*=	x = 7, x *= 2	x refers to 14
/=	x = 7, x /= 2	x refers to 3.5
//=	x = 7, x //= 2	x refers to 3
%=	x = 7, x %= 2	x refers to 1
**=	x = 7, x **=2	x refers to 49
