Explain & Practice

Greater than (>)

Operators (>)

Example case 6>5 result is true ( true).

Code example

void main() {
   print(6>5);
}

The result is

true

Smaller than (<)

Operators (<)

Example case 6<5 the result is true ( false).

Code example

void main() {
   print(6<5);
}

The result is

false

Greater or equal to (>=)

Operators (>=)

Example case 6>=5 result is  (true)

code example

void main() {
   print(6>=5);
}

The result is

true

Example of the 2nd case:

5 >= 5 the result is (true)

code sample 

void main() {
   print(5>=5);
}

The result is

true

Smaller than or equal to (<=)

Operators (<=)

Example case 6<=5 the result is   (false)

code example

void main() {
   print(6<=5);
}

The result is

false

Example of the 2nd case:

5 <= 5 the result is  (true)

code sample 

void main() {
   print(5<=5);
}

The result is

true

Same as (==)

operator (==)

Example:

divine == goddess result is (false)

code example

void main() {
   print("virtue"=="goddess");
}

The result is

false

Not the same as (!=)

operators (!=)

Example:

budi != goddess result is (true)

code example

void main() {
   print("virtuous"!="goddess");
}

The result is

true

Is

operator (is)

Example:

0.1 is int result is ( false)

code example

void main() {
   print(0.1 is int);
}

The result is

false

Is not (is!)

operator (is!)

Example:

0.1 is not int the result is ( true)

code example

void main() {
   print(0.1 is! int);
}

The result is

true
