The conditional operators (&&, ||) allow performing a logical AND (&&) or logical OR (||) on its two boolean operands.
The AND (&&) operator returns true only if both of its operands are true.

 | bool b1;b1 = false && false;    // falseb1 = false && true;     // falseb1 = true && false;     // falseb1 = true && true;      // true | 
The OR (||) operator returns true if at least one of its operands is true.

 | b1 = false || false;    // falseb1 = false || true;     // trueb1 = true || false;     // trueb1 = true || true;      // true | 
You’d normally use boolean variables in expressions where conditional operators are used, e.g.:
1 
2 
 | bool goForWalk = niceWeather && lightOutside;bool callPolice = seeBurglar || brokeALimb; |
