Operators

Hello! Since almost any code requires operators and operators are one of the most important things in programming I thought I would make a post in which I am talking about them! Hope this helps you!

Enjoy!

First, what is an “operator”?

An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations and there are multiple types of operators, the most common of them being arithmetic operators and logical operators.

Arithmetic Operators

There are following arithmetic operators supported by C++ language:

Assume variable A holds 10 and variable B holds 20, then:

Operator Description Example
+ Adds two operands A + B will give 30
Subtracts second operand from the first A – B will give -10
* Multiplies both operands A * B will give 200
/ Divides numerator by de-numerator B / A will give 2
% Modulus Operator and remainder of after an integer division B % A will give 0
++ Increment operator, increases integer value by one A++ will give 11
Decrement operator, decreases integer value by one A– will give 9

Relational Operators

There are following relational operators supported by C++ language

Assume variable A holds 10 and variable B holds 20, then:

Operator Description Example
== Checks if the values of two operands are equal or not, if yes then condition becomes true. (A == B) is not true.
!= Checks if the values of two operands are equal or not, if values are not equal then 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 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 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 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 then condition becomes true. (A <= B) is true.

Logical Operators

There are following logical operators supported by C++ language

Assume variable A holds 1 and variable B holds 0, then:

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.

Keep on coding 😉 !
