bookLogical Operators

You have to use the logical operators NOT (!), AND (&&), and OR (||) to evaluate multiple conditions concurrently. Let's illustrate using logical operators in real-life scenarios:

  • I will take my wallet for a walk if there is a bank AND a shop on the way;
  • I won't take my wallet for a walk if there is NOT bank on the way;
  • I will take my wallet for a walk if there is a bank OR a shop on the way.
cpp

main

copy

#include <iostream>

int main()
{
	bool bank = true; 
	bool shop = true;

	//using AND (&&) operator
	bool wallet1 = (bank && shop);
	std::cout << "There is a bank and a shop, reason to have wallet = " << wallet1 << std::endl;

	//using NOT (!) operator
	bool wallet0 = (!bank);
	std::cout << "There is not bank, reason to have wallet = " << wallet0 << std::endl;

	//using OR (||) operator
	bool wallet2 = (bank || shop);
	std::cout << "There is a bank or a shop, reason to have wallet = " << wallet2 << std::endl;
}
