Operator

Pada sesi ini kita akan membahas operator yang dapat digunakan pada Go

Assignment Operator

Operator	Description	Example
=	Simple assignment operator, Assigns values from right side operands to left side operand	C = A + B will assign value of A + B into C
+=	Add AND assignment operator, It adds right operand to the left operand and assign the result to left operand	C += A is equivalent to C = C + A
-=	Subtract AND assignment operator, It subtracts right operand from the left operand and assign the result to left operand	C -= A is equivalent to C = C - A
*=	Multiply AND assignment operator, It multiplies right operand with the left operand and assign the result to left operand	C *= A is equivalent to C = C * A
/=	Divide AND assignment operator, It divides left operand with the right operand and assign the result to left operand	C /= A is equivalent to C = C / A
%=	Modulus AND assignment operator, It takes modulus using two operands and assign the result to 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

Arithmetic Operator

Operator	Description	Example
+	Adds two operands	A + B gives 30
-	Subtracts second operand from the first	A - B gives -10
*	Multiplies both operands	A * B gives 200
/	Divides the numerator by the denominator.	B / A gives 2
%	Modulus operator; gives the remainder after an integer division.	B % A gives 0
++	Increment operator. It increases the integer value by one.	A++ gives 11
--	Decrement operator. It decreases the integer value by one.	A-- gives 9

Comparison Operator

Operator	Description	Example
==	It checks if the values of two operands are equal or not; if yes, the condition becomes true.	(A == B) is not true.
!=	It 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.
>	It checks if the value of left operand is greater than the value of right operand; if yes, the condition becomes true.	(A > B) is not true.
<	It checks if the value of left operand is less than the value of the right operand; if yes, the condition becomes true.	(A < B) is true.
>=	It checks if the value of the left operand is greater than or equal to the value of the right operand; if yes, the condition becomes true.	(A >= B) is not true.
<=	It checks if the value of left operand is less than or equal to the value of right operand; if yes, the condition becomes true.	(A <= B) is true.

Logical Operator

Operator	Description	Example
&&	Called Logical AND operator. If both the operands are non-zero, then condition becomes true.	(A && B) is false.
||	Called Logical OR Operator. If any of the two operands is non-zero, then condition becomes true.	(A || B) is true.
!	Called Logical NOT Operator. Use to reverses the logical state of its operand. If a condition is true then Logical NOT operator will make false.	!(A && B) is true.
