# Conditional logical operator in C Sharp

What is a conditional logical operator in C Sharp?
A conditional logical operator in C # contains a conditional AND operator (&&) and a conditional OR operator (||). It is a conditional version of a logical Boolean operator (& and |).

Conditional logical operators are used in decision instructions that determine the path of execution based on the condition, which is specified as a combination of several Boolean expressions. They are useful in generating efficient code by ignoring unnecessary logic and saving execution time, especially for logical expressions that use multiple conditional operators.

In contrast to the Boolean logical operators '&' and '|,', which always evaluate both operands, conditional logical operators only execute the second operand when necessary. As a result, conditional logical operators are faster than Boolean logical operators and are often preferred. The execution with the conditional logical operators is called 'short circuit' or 'lazy' evaluation.

Conditional logical operators are also known as logical short circuits.

The conditional AND operator (&&) is used to perform a logical AND of its Boolean type operands. The second operand is only evaluated if it is necessary. It is similar to the logical Boolean operator '&', except that the second operand is not evaluated if the first operand returns the value false. This is because the '&&' operation is only true if the evaluation of both operands results in true.

The conditional OR operator (||) is used to logically OR its boolean operands. The second operand is not evaluated if the first operand is evaluated as true. It differs from the logical Boolean operator '|' by performing a 'short circuit' evaluation, whereby the second operand is not evaluated if the first operand is evaluated as true. This is due to the fact that the result of the '||' Operation is true if the evaluation of either operand is true.

For example, to validate a number that is within an upper and a lower bound, the logical AND operation can be performed on the two conditions looking for the upper and lower bounds expressed as Boolean expressions.

Conditional logical operators are left-associative, which means that they are evaluated in left-to-right order in an expression in which these operators exist in multiple occurrences.
