Golang Programming Operators

Operators are symbols that tell the compiler to perform specific operations that may be mathematical, relational or logical. The Golang programming language has a rich in in-built operators that can be grouped into: Arithmetic Operators, Relational Operators, Logical Operators, Bitwise Operators, Assignment Operators and the Misc Operators.

So, let’s dive in and find out about these operators:

#1: Arithmetic Operators
Here are examples of Golang’s arithmetic operators and their uses:

• • “

+

• ” It adds two operands. For instance if A=20 and B=20 then A+ gives 40 as the answer.

• • “

–

• ” It subtracts the second operand from the first operand. For example, if A=20 and B=20 then A – B will yield 0.

• • “

*

• ” It’s used for multiplication of operands. For example, A*B produces 400.

• • “

/

• ” It’s used for division. For instance, A/B produces 1.

• • “

%

• ” It’s a modulus operator—it displays the remainder of a number after an integer division. For instance, B % A yields 0 as a remainder.

• • “

++

• ” It’s an increment operator—it increases integer value by one. For instance, A++ yields 21.

• • “

—

” It’s a decrements operator—it decreases an integer value by one.

#2: Relational Operators
Here are examples of Golang’s relational operators and their uses:

• • “

==

• ” It checks whether the values of two operands are equal or not. If they are equal, the condition becomes true. For instance A==B is true if A=20 and B=20.

• • “

!=

• ” It checks whether the values of two operands are equal or not. For instance, A!=B is false.

• • “

>

• ” It checks whether the value of the left operand is greater than what is on the right operand.

• • “

<

• ” It checks whether the value of the left operand is less than what is on the right operand.

• • “

>=

• ” It checks whether the value of the left operand is greater than or equal to what is on the right operand.

• • “

<=

” It checks whether the value of the left operand is less than or equal to what is on the right operand.

#3: Logical Operators
Here are examples of Golang’s logical operators and their uses:

• • “

&&

• ” the logical AND operator. If both the operands are not zero, then condition is true.

• • “

||

• ” the logical OR operator. If any of two operands is not zero, then condition is true.

• • “

!

” the logical NOT Operator. It reverses the logical state of its initial operand.

#4: Bitwise Operators
The bitwise operators performs bit-by-bit operations in programming. Here are examples of Golang’s bitwise operators and their uses:

• • “

&

• ” the binary AND operator. It copies a bit to the result if it is existing in both the operands.

• • “

|

• ” the binary OR operator. It copies a bit if it is existing in either operand.

• • “

^

• ” the binary XOR operator. It copies the bit if it is set in only one operand and not both operators.

• • “

<<

• ” the binary left shift operator. It moves the left side by a number of bits that are specified by the right operand.

• • “

>>

” the binary right shift operator. It moves the right side by a number of bits that are specified by the right operand.

#5: Assignment Operators
Here are examples of Golang’s assignment operators and their uses:

• • “

=

• ” It assigns values from right side operands to the left side operand.

• • “

+=

• ” It adds the right operand to left operand and assign the answer to left operand.

• • “

-=

• ” It subtracts the right operand to left operand and assign the answer to left operand.

• • “

*=

• ” It multiplies the right operand to left operand and assign the answer to left operand.

• • “

/=

” It divides the right operand to left operand and assign the answer to left operand.

#6: Misc Operators
Here are examples of Golang’s misc operators and their uses:

• • “

&

• ” It returns the address of a given variable.

• • “

*

” It’s a pointer to a particular variable.
