Golang Operators
 An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations. Go language is rich in builtin operators and provides the following types of operators

Arithmetic Operators in go language programming
 Considering variable x = 6 and Y = 2. Let’s see how it works,
Operator  Description  Example 

+  Adds two operands  X + Y will give 8 
  Subtracts second operand from the first  X  Y will give 4 
*  Multiplies both operands  X * Y will give 12 
/  Divides numerator by denumerator  Y / X will give 3 
%  Modulus Operator and remainder of after an integer division  Y % X will give 0 
++  Increments operator increases integer value by one  X++ will give 7 
  Decrements operator decreases integer value by one  X will give 5

Relational Operators in go language programming
 Considering I got the variable x = 6 and Y = 2
Show Examples
Operator  Description  Example 

==  Checks if the values of two operands are equal or not, if yes then condition becomes true. 
(X == Y) is not true. 
!=  Checks if the values of two operands are equal or not, if values are not equal then condition becomes true. 
(X != Y) is true. 
>  Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true. 
(X > Y) is not true. 
<  Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true. 
(X < Y) is true. 
>=  Checks if the value of left operand is greater than right operand, if yes then condition becomes true. 
(X >= Y) is not true 
<=  Checks if the value of left operand is less than if yes then condition becomes true. 
(X <= Y) is true.

Logical Operators in go language programming
 Following table shows all the logical operators supported by Go language. Assume variable X holds 1 and variable Y holds 0, then:
Show Examples
Operator  Description  Example 

&&  Called Logical AND operator. If both the operands are nonzero, then condition becomes true. 
(X && Y) is false. 
  Called Logical OR Operator. If any of the two operands is nonzero, then condition becomes true. 
(X  Y) 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. 
!(X && Y) is true.

Bitwise Operators in go language programming
 Bitwise operator works on bits and perform bitbybit operation.
 The truth tables for AND, OR , NOT is given below,
p  q  p & q  p  q  p ^ q 

0  0  0  0  0 
0  1  0  1  1 
1  1  1  1  1 
1  0  0  1  1 
 Assume if X = 60; and Y = 13; now in binary format they will be as follows:
 The Bitwise operators supported by C language are listed in the following table. Assume variable X holds 60 and variable Y holds 13, then:
Operator  Example  

& 

(X & Y) will give 12, which is 0000 1100 
 

(X  Y) will give 61, which is 0011 1101 
<< 

X << 2 will give 240 which is 1111 0000 
^ 

(X ^ Y) will give 49, which is 0011 0001 
>> 

X >> 2 will give 15 which is 0000 1111

Assignment Operators in go language programming
 There are following assignment operators supported by Go language
golang , gopro , google go , golang tutorial , google language , go language , go programming language
Show Examples
Operator  Example  

= 

C = X + Y will assign value of X + Y into C 
+= 

C += X is equivalent to C = C + X 
= 

C = X is equivalent to C = C  X 
*= 

= C * X 
/= 

C /= X is equivalent to C = C / X 
%= 

C %= X is equivalent to C = C % X 
<<=  39GwAQ7PeH7fJTFa4DXguurfn7GULq2pTs  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 
Misc Operators in go language programming
Operator  Example  

&  Returns the address of an variable  &a; will give actual address of the variable. 
*  Pointer to a variable.  *a; will pointer to a variable. 
Operators Precedence in go language programming
 Operator precedence determines the grouping of terms in an expression. This affects how an expression is evaluated. Certain operators have higher precedence than others.
 For example, the multiplication operator has higher precedence than the addition operator.
 For example,
 Following table lists all operators from highest precedence to lowest.
method  Description  

Yes  * / % >> << &  Multiply, divide, modulo, Right and left bitwise shift, Bitwise 'AND' 
Yes  +   ^  Addition and subtraction, regular `OR', Bitwise exclusive `OR' 
Yes  <= < > >= == !=  Comparison operators, Equality and pattern match operators (!= may not be defined as methods) 
&&  Logical 'AND'  
  Logical 'OR'
