Programming in C MCQ - Operators and Expressions
The += compound assignment adds b to the current value of a and stores the result back in a, making it equivalent here to a = a + b.
== tests whether two operands are equal. A single = is the assignment operator rather than an equality comparison.
&& is the logical AND operator. It combines logical conditions and is distinct from the single & bitwise AND operator.
! is the logical NOT operator. It negates the logical truth value of its operand.
