WebNov 21, 2024 · The direct assignment operator expects a modifiable lvalue as its left operand and an rvalue expression or a braced-init-list (since C++11) as its right operand, and returns an lvalue identifying the left operand after modification. The result is a bit-field if the left operand is a bit-field. WebThe operator ! is the C++ operator for the Boolean operation NOT. It has only one operand, to its right, and inverts it, producing false if its operand is true, and true if its operand is false. Basically, it returns the opposite Boolean value of evaluating its operand. For example:

WebComparison Operators. Comparison operators are used to compare two values (or variables). This is important in programming, because it helps us to find answers and make decisions.
