C# If Statements - Logical Operators

What are the logical operators used in C# if statements?

• ||

• &

• ^

• &&, ||, !

How do you represent 'AND' in C# if statements?

• &

• &&

• ||

• AND

How do you represent 'OR' in C# if statements?

• Use the '==' operator

• Use the '&&' operator

• Use the '!' operator

• Use the '||' operator

What is the result of 'true && false' in C#?

• false

• true

• true

• true

What is the result of 'true || false' in C#?

• 0

• true

• null

• false

How do you negate a condition in C# if statements?

• Add '!' before the condition in the if statement.

• Remove the condition from the if statement

• Use '&&' before the condition in the if statement

• Add 'not' before the condition in the if statement

What is short-circuit evaluation in C# if statements?

• Short-circuit evaluation in C# if statements means evaluating both conditions simultaneously

• Short-circuit evaluation in C# if statements is a mechanism where the second condition is only evaluated if the first condition is false.

• Short-circuit evaluation in C# if statements is a feature that only works in loops, not if statements

• Short-circuit evaluation in C# if statements always evaluates the second condition first

Explain the difference between '&&' and '||' in C# if statements.

• '&&' is used for bitwise operations, while '||' is used for logical comparisons.

• '&&' is the logical OR operator, requiring both conditions to be true, while '||' is the logical AND operator, requiring at least one condition to be true.

• '&&' is used for string concatenation, while '||' is used for bitwise operations.

• '&&' is the logical AND operator, requiring both conditions to be true, while '||' is the logical OR operator, requiring at least one condition to be true.

What happens if the first condition in an '&&' operation is false in C#?

• The second condition is not evaluated

• The entire '&&' operation is skipped

• An error is thrown

• The second condition is evaluated regardless

What happens if the first condition in an '||' operation is true in C#?

• The first condition will be skipped.

• The '||' operation will throw an error.

• The second condition will not be evaluated.

• The second condition will always be evaluated.
