  Operato r Description Exampl e && CalledLogical AND operator. If both the operands are non-zero, then the condition becomes true. (A && B) is false. || Called Logical OR Operator. If any of the two operands is non-zero, then the condition becomes true. (A || B) is true. ! Called Logical NOT Operator. It is used to reverse the logical state of its operand. If a condition is true, then Logical NOT operator will make it false. !(A && B) is true.

  Operato r Description Example + Addstwo operands. A + B = 30 − Subtracts second operand from the first. A − B = -10 * Multiplies both operands. A * B = 200 / Divides numerator by de-numerator. B / A = 2 % Modulus Operator and remainder of after an integer division. B % A = 0 ++ Increment operator increases the integer value by one. A++ = 11 -- Decrement operator decreases the integer value by one. A-- = 9

  •Rules of operator precedence •Operators in parentheses evaluated first • Multiplication, division, modulus applied next • Addition, subtraction applied in last • Operators applied from left to right

  Operato r Description Example == Checksif the values of two operands are equal or not. If yes, then the condition becomes true. (A == B) is not true. != Checks if the values of two operands are equal or not. If the values are not equal, then the condition becomes true. (A != B) is true. > Checks if the value of left operand is greater than the value of right operand. If yes, then the condition becomes true. (A > B) is not true. < Checks if the value of left operand is less than the value of right operand. If yes, then the condition becomes true. (A < B) is true. >= Checks if the value of left operand is greater than or equal to the value of right operand. If yes, then the condition becomes true. (A >= B) is not true. <= Checks if the value of left operand is less than or equal to the value of right operand. If yes, (A <= B) is true.

  Operato r Description Example = Simpleassignment operator. Assigns values from right side operands to left side operand C = A + B will assign the value of A + B to C += Add AND assignment operator. It adds the right operand to the left operand and assign the result to the left operand. C += A is equivalent to C = C + A -= Subtract AND assignment operator. It subtracts the right operand from the left operand and assigns the result to the left operand. C -= A is equivalent to C = C - A *= Multiply AND assignment operator. It multiplies the right operand with the left operand and assigns the result to the left operand. C *= A is equivalent to C = C * A /= Divide AND assignment operator. It divides the left operand with the right operand and assigns the result to the left operand. C /= A is equivalent to C = C / A

  %= Modulus ANDassignment operator. It takes modulus using two operands and assigns the result to the left operand. C %= A is equivalent to C = C % A <<= Left shift AND assignment operator. C <<= 2 is same as C = C << 2 >>= Right shift AND assignment operator. C >>= 2 is same as C = C >> 2 &= Bitwise AND assignment operator. C &= 2 is same as C = C & 2 ^= Bitwise exclusive OR and assignment operator. C ^= 2 is same as C = C ^ 2 |= Bitwise inclusive OR and assignment operator. C |= 2 is same as C = C | 2
