C++ Logical Operators

Logical operators in C++ are used to combine multiple conditions or to invert the value of a condition. These operators return a boolean value, either true or false, based on the result of the logical operation. This guide will explore each logical operator and provide examples of their usage.

List of Logical Operators

  • && : Logical AND
  • || : Logical OR
  • ! : Logical NOT

Usage and Examples

1. Logical AND (&&)

Returns true if both conditions are true. Otherwise, it returns false.

bool isAdult = true;
bool hasLicense = true;

if (isAdult && hasLicense) {
    std::cout << "Allowed to drive." << std::endl;
}

2. Logical OR (||)

Returns true if at least one of the conditions is true. If both are false, it returns false.

bool isWeekend = true;
bool isHoliday = false;

if (isWeekend || isHoliday) {
    std::cout << "Enjoy your day off!" << std::endl;
}

3. Logical NOT (!)

Inverts the value of a condition. If the condition is true, it returns false and vice versa.

bool isRaining = false;

if (!isRaining) {
    std::cout << "It's a sunny day!" << std::endl;
}

Combining Logical Operators

You can combine multiple logical operators to evaluate complex conditions:

bool hasHomework = true;
bool isWeekend = true;
bool isSick = false;

if ((isWeekend || isSick) && !hasHomework) {
    std::cout << "You can relax today." << std::endl;
} else {
    std::cout << "You have some responsibilities." << std::endl;
}

Conclusion

Logical operators are essential tools in C++ programming, allowing for complex decision-making based on multiple conditions. Understanding and using these operators correctly is crucial for writing clear and efficient programs.
