• # Operators

Logical operators in programming are like a set of tools that help us decide what to do depending on how things look. Logical operators tell the computer to do something based on how two different things compare.

• ## Increment Operators

• The increment operator increments the value of a single variable.

• #### D

##### Example of increment operator in d.
``````import std.stdio : write;

void main()
{
int age = 20;

// Increment After
write(age++); // 20
write(age); // 21

// Increment Before
write(++age); // 22
write(age); // 22
}
``````
• ## Decrement Operators

• The decrement operator decrements the value of a single variable.

• #### D

##### Example of decrement operator in d.
``````import std.stdio : write;

void main()
{
int age = 20;

// Decrement After
write(age--); // 20
write(age); // 19

// Decrement Before
write(--age); // 18
write(age); // 18
}
``````

• The equal operator checks if two variables are equal value.

• #### D

##### Example of equal operator in d.
``````import std.stdio : write;

void main()
{
int age = 20;

write(age == 20); // true
}

import std.string;

void main()
{
string age = "20";

write(age == "20"); // true
}
``````
• ## Not Equal Comparison Operators

• The not-equal operator checks if two variables are not equal value.

• #### D

##### Example of not-equal operator in d.
``````import std.stdio : write;
