Toán tử trong Go

1. Toán tử số học

Với A := 10 và B := 20

2. Toán tử so sánh

Với A := 10 và B := 20

3. Toán tử logical

Với A := true và B := false

4. Toán tử bitwise

Ví dụ: Với A := 60 và B:= 13

A = 0011 1100
B = 0000 1101
-----------------
A&B = 0000 1100
A|B = 0011 1101
A^B = 0011 0001
~A  = 1100 0011

#	Operator	Description	Example
1	&	Binary AND Operator copies a bit to the result if it exists in both operands.	(A & B) will give 12, which is 0000 1100
2	\|	Binary OR Operator copies a bit if it exists in either operand.	(A \| B) will give 61, which is 0011 1101
3	^	Binary XOR Operator copies the bit if it is set in one operand but not both.	(A ^ B) will give 49, which is 0011 0001
4	<<	Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand.	A << 2 will give 240 which is 1111 0000
5	>>	Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand.	A >> 2 will give 15 which is 0000 1111

#	Operator	Description	Example
1	=	Simple assignment operator, Assigns values from right side operands to left side operand	C = A + B will assign value of A + B into C
2	+=	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
3	-=	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
4	*=	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
5	/=	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
6	%=	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
7	<<=	Left shift AND assignment operator	C <<= 2 is same as C = C << 2
8	>>=	Right shift AND assignment operator	C >>= 2 is same as C = C >> 2
9	&=	Bitwise AND assignment operator	C &= 2 is same as C = C & 2
10	^=	bitwise exclusive OR and assignment operator	C ^= 2 is same as C = C ^ 2
11	\|=	bitwise inclusive OR and assignment operator	C \|= 2 is same as C = C \| 2

6. Toán tử khác

#	Operator	Description	Example
1	&	Returns the address of a variable.	&a; provides actual address of the variable.
2	*	Pointer to a variable.	*a; provides pointer to a variable.
