Which operator is true only when both the operands are true?
&&
Remarks. The logical AND operator (&&) returns true if both operands are true and returns false otherwise. The operands are implicitly converted to type bool before evaluation, and the result is of type bool . Logical AND has left-to-right associativity.
Can an expression be evaluated as true or false?
Value or expression that can be evaluated as true or false is called a boolean.
Is true and false false?
BOTH conditions have to evaluate to true (have to be true) before the entire expression is true. True is written: true; False is written: false; Not is written in a variety of ways.
Will evaluate to TRUE?
An expression using the OR operator will evaluate to TRUE if the left operand or the right operand is TRUE. If both are TRUE, the expression will evaluate to TRUE, however if neither are TRUE, then the expression will be FALSE.
Which is true if the operand evaluates to false?
That is, it produces true, if the operand evaluates to false, and false, if the operand evaluates to true: Beginning with C# 8.0, the unary postfix ! operator is the null-forgiving operator. The & operator computes the logical AND of its operands. The result of x & y is true if both x and y evaluate to true. Otherwise, the result is false.
Is the logical OR operator true or false?
|| the logical OR operator. ?: the ternary operator. The logical AND and logical OR operators both take two operands. Each operand is a boolean expression (i.e., it evaluates to either true or false). The logical AND condition returns true if both operands are true, otherwise, it returns false.
Why does the operator not evaluate the second operand?
In other words, if the first operand determines the overall value for the condition, then the second operand is not evaluated. For example, if the logical OR operator evaluates its first operand to be true, it does not need to evaluate the second one because it already knows the logical OR condition has to be true.
Is the result of logical expression a.or.b false?
Therefore, the result of logical expression a .OR. b is .FALSE. if and only if both operands a and b are .FALSE.. In all other cases, the result is always .TRUE. In other words, if one of the two operands of the .OR. operator is .TRUE., the result is .TRUE. The following is the truth table of .EQV.
