C++ Logical Operators - Cyborg Coding

C++ includes several logical operators that can be used to evaluate the logical relationship between two expressions and determine whether they are true or false. The most commonly used logical operators in C++ are:

Logical AND (&&): This operator is used to determine if two expressions are both true. It returns true if both expressions are true, and false if either expression is false.

Logical OR (||): This operator is used to determine if at least one of two expressions is true. It returns true if either expression is true, and false if both expressions are false.

Logical NOT (!) : This operator is used to negate the value of a single expression. It returns true if the expression is false and false if the expression is true.

Here's an example of how these operators can be used:

bool a = true;

bool b = false;

bool andResult = (a && b); // false

bool orResult = (a || b); // true

bool notAResult = !a; // false

In this example, the variables a and b are assigned the values true and false, respectively. The logical AND operator (&&) is used to evaluate whether both a and b are true, which is not the case, therefore it returns false. The logical OR operator (||) is used to evaluate whether at least one of a and b is true, which is the case, therefore it returns true. The logical NOT operator (!) is used to negate the value of a and returns false

It's important to note that the logical AND operator (&&) and logical OR operator (||) are short-circuit operators in C++, which means if the first operand is enough to determine the result, the second operand will not be evaluated.

It's also important to note that, the logical operator && and || only return true or false and not the actual value of the operands, this means that the following expression x = a && b will not assign the value of b to x if a is true, x will be assigned the value of true.
