What is an operator?
Operator is an symbol in programming that performsn an operation on operands
Syntax
operand1 operator operand2
There are two types of operators.
- Binary Operator: It operates on two operands such as addition, subtraction, multiplication, division, and modulus
- unary operator: It operats on single operand such as increment and decrement
Dart supports multiple operators
- Arithmetic Operators
- Relational Operators
- Assignment Operators
- Logical Operators
- Bitwise Operators
- Other Operators
Dart Arithmetic Operators
Arithmetic operators in Dart provide arithmetic operations such as add, division, subtraction, and division multiplication operators.
| Operator | Title | Description | Example |
|---|---|---|---|
| + | Addition | addition of two or more operands | p+q=50 |
| - | Subtraction | subtraction of two or more operands | q-p=10 |
| * | Multiplication | multiplication of two or more operands | p*q=600 |
| / | Divide | results quotient after the division of values | q/p=1.5 |
| % | Modulus | Return the remainder after the division of values | q%p=10 |
| % | Modulus | Return the remainder after the division of values | q%p=10 |
| -expr | Unary Minus | reverse of an expression | -(10-7) is -3 |
| ~/ | Division Int | returns division int value | (10~/7) is 1 |
| ++ | Increment | Increment the value by 1 | ++p=21 |
| -- | Decrement | Decrement the value by 1 | --q=29 |
Here is an arithmetic operator example
void main() {
var m = 25;
var n = 4;
print("m+n - ${m + n}");
print("++m - ${++m}");
print("m++ - ${m++}");
print("--m - ${--m}");
print("m-- - ${m--}");
print("m-n - ${m - n}");
print("m/n - ${m / n}");
print("m*n - ${m * n}");
print("m%n - ${m % n}");
print("m~/n - ${m ~/ n}");
}
Output:
m+n - 29
++m - 26
m++ - 26
--m - 26
m-- - 26
m-n - 21
m/n - 6.25
m*n - 100
m%n - 1
m~/n - 6
