C#.NET — Which of the following is NOT an assignment operator?

Question

Solve this multiple-choice question and choose the correct option.

Accepted Answer

Introduction / Context:C# provides simple and compound assignment operators for updating variables concisely. Identifying invalid tokens prevents syntax errors. Given Data / Assumptions: Valid compound assignments include +=, -=, =, /=, %=, &=, |=, ^=, <<=, >>=. The simple assignment operator is =. The token "\=" (backslash-equals) is not a C# operator. Concept / Approach:Compare each choice against the C# operator set. Anything not in the set is invalid. Step-by-Step Solution: Check "/=" → valid (divide-and-assign).Check "=" → valid (multiply-and-assign).Check "+=" → valid (add-and-assign).Check "%=" → valid (mod-and-assign).Check "\=" → invalid; no such operator exists in C#. Verification / Alternative check:Attempting to compile x \= y; yields a compile-time error, while x += y; and x /= y; compile. Why Other Options Are Wrong:B–E are all standard compound assignment operators defined by the language. Common Pitfalls:Confusing escape characters in strings with operator tokens; backslash is not an operator character in assignment. Final Answer:\=
