Day 8 : C++Language| Logical Operators

Logical Operators

The three most commonly used logical operators are AND, OR, and NOT


AND (&&)

This operator requires that all connected conditions be true for the overall statement to be true.


For instance, in programming, if A and B represent conditions, A AND B returns true only if both A and B are true.






#include
using namespace std;

int main() {
int x = 6;
int y = 4;

cout 3 && x
// returns true (1) because 6 is greater than 3 AND 4 is less than 10 .

//since both statement are true , result will be true satisfying and operator

return 0;
}







OR ( || )

This operator allows for flexibility—only one of the connected conditions must be true.


In the statement A OR B, the result will be true if either A or B (or both) is true.






#include
using namespace std;

int main() {
int x = 5;
int y = 3;
cout 1 || x
// returns true (1) because one of the conditions are true
(5 is greater than 1, but 5 is not less than 3)

return 0;

}







NOT (!)

NOT inverts the truth value of a single condition.

If A is true, then NOT A will be false, and vice versa.






#include
using namespace std;

int main() {
int x = 6;
int y = 4;

cout 3 && x // returns false (0) because ! (not) is used to reverse the result

return 0;
}







Uses of logical operators

They are implemented in conditional statements, loops, and algorithms to enable computers to make decisions.

For example, imagine an e-commerce platform where discounts are applied only if a customer is both a loyalty member AND has spent over a certain amount.





Logical operators will be explained in detail while learning loops
