4. Which is not an Assignment Operator?

(1) =
(2) / =
(3) + =
(4) !=

Correct Answer: (4) !=

Solution:Assignment operators are used to assigning value to a variable. The left side operand of the assignment operator is a variable and right side operand of the assignment operator is a value. The value on the right side must be of the same data-type of the variable on the left side otherwise the compiler will raise an error.

Different types of assignment operators are:

"=": This is the simplest assignment operator. This operator is used to assign the value on the right to the variable on the left;

"+=": This operator is combination of '+' and '=' operators. This operator first adds the current value of the variable on left to the value on the right and then assigns the result to the variable on the left;

"/=": This operator is combination of '/' and '=' operators. This operator first divides the current value of the variable on left by the value on the right and then assigns the result to the variable on the left.
