13.2 Assignment Operators
Assignment. This binary operator causes the value of the right operand to be assigned to the left operand.
Assignments can be “cascaded” as shown in this example.
a = 10 * b + c; // a gets the result of the calculation
a = b = 0; // b gets 0 and a gets 0
Addition assignment.
a += 5; // Add 5 to a. Same as a = a + 5
Subtraction assignment.
a -= 5; // Subtract 5 from a. Same as a = a - 5
Multiplication assignment.
a *= 5; // Multiply a by 5. Same as a = a * 5
Division assignment.
a /= 5; // Divide a by 5. Same as a = a / 5
Modulo assignment.
a %= 5; // a mod 5. Same as a = a % 5
Left shift assignment.
a <<= 5; // Shift a left 5 bits. Same as a = a << 5
