✐ Examples
1 Check if a positive integer is even
In this example,
- We create an integer variable
number1
with the value 10. - We access its
isEven
property to check if it is even. - We then print the result to standard output.
Dart Program
void main() {
int number1 = 10;
bool isEven1 = number1.isEven;
print('$number1 is even: $isEven1');
}
Output
10 is even: true
2 Check if a positive integer is odd
In this example,
- We create an integer variable
number2
with the value 7. - We access its
isEven
property to check if it is even. - We then print the result to standard output.
Dart Program
void main() {
int number2 = 7;
bool isEven2 = number2.isEven;
print('$number2 is even: $isEven2');
}
Output
7 is even: false
3 Check if a negative integer is even
In this example,
- We create an integer variable
negativeNumber
with the value -6. - We access its
isEven
property to check if it is even. - We then print the result to standard output.
Dart Program
void main() {
int negativeNumber = -6;
bool isEvenNegative = negativeNumber.isEven;
print('$negativeNumber is even: $isEvenNegative');
}
Output
-6 is even: true
