Logical Operator

Logical operators are used to determine the logic between variables or values:

Operator	Name	Description	Example
&&	Logical and	Returns true if both statements are true	x < 5 && x < 10
||	Logical or	Returns true if one of the statements is true	x < 5 || x < 4
!	Logical not	Reverse the result, returns false if the result is true	!(x < 5 && x < 10)

    
        #include<stdio.h>

        int main() {
            int x = 5;
            int y = 3;

            // Returns 1 (true) because 5 is greater than 3 AND 5 is less than 10
            printf("%d", x > 3 && x < 10);
            return 0;
        }

            int x = 5;
            int y = 3;
            printf("%d", x != y); // returns 1 (true) because 5 is not equal to 3
            return 0;

            // Returns false (0) because ! (not) is used to reverse the result
            printf("%d", !(x > 3 && x < 10));
            return 0;
