C# short circuiting and non-short-circuiting operators

 In C#, short-circuiting refers to the behavior where the second operand of a logical expression is evaluated only if the first operand doesn't already determine the final result. 

Short-Circuiting Operators

These operators are formally known as conditional logical operators. 

• && (Conditional AND): If the left-hand operand is false, the overall result must be false, so the right-hand operand is not evaluated.
• || (Conditional OR): If the left-hand operand is true, the overall result must be true, so the right-hand operand is not evaluated.
• ?. and ?[] (Null-conditional): These "short-circuit" by returning null immediately if the operand to the left is null, preventing the evaluation of the rest of the member access chain.
• ?? (Null-coalescing): Evaluates the right-hand operand only if the left-hand operand evaluates to null. 

Non-Short-Circuiting Operators

These operators always evaluate both operands, regardless of the result of the first one. 

• & (Logical AND): When used with bool operands, it computes the logical AND but always evaluates both sides.
• | (Logical OR): When used with bool operands, it computes the logical OR but always evaluates both sides.
• ^ (Logical Exclusive OR): Always evaluates both operands to determine if exactly one is true.
