Logical Operators An expression containing logical operator returns either 0 or 1 depending upon whether expression results true or false. Logical operators are commonly used in decision making in C programming . Operator Meaning of Operator Example && Logial AND. True only if all operands are true If c = 5 and d = 2 then, expression ((c == 5) && (d > 5)) equals to 0. || Logical OR. True only if either one operand is true If c = 5 and d = 2 then, expression ((c == 5) || (d > 5)) equals to 1. ! Logical NOT. True only if the operand is 0 If c = 5 then, expression ! (c == 5) equals to 0. Arithmetic Operators An arithmetic operator performs mathematical operations such as addition, subtraction and multiplication on numerical values (constants and variables). Operator Meaning of Operator + addition or unary plus - subtraction or unary minus * multiplication / division % remainder after division( modulo division).
