What are assignment operators?

• A. Operators used to compare values
• B. Operators used to assign values to variables
• C. Operators used to increment values only
• D. Operators used to subtract values

Answer: (B)

Assignment operators are used to put a value into a variable, or to update the value stored in that variable. The simplest form is the equals sign, which takes the value on the right and stores it in the variable on the left, as in a = 10. This is how you initialize variables and keep track of data. There are also compound forms that combine an operation with assignment in one step, such as a += 5 (add 5 to a and store the result back in a), a -= 3, a *= 2, and a /= 4. These are handy for updating a variable based on its current value. This is different from comparison operators that only check whether values are equal, and not from arithmetic operators that compute a result without necessarily storing it. An increment like x = x + 1 is still an assignment, and x += 1 does the same in a shorter form.
