Increment and Decrement
Increment (++) and decrement (--) operators are commonly used to increase or decrease a variable's value by 1. They are especially useful in loops for managing counters.
Increment Operators
- Pre-increment (
++variable): increases the value before usage; - Post-increment (
variable++): increases the value after usage.
Usage in a loop:
main
void main() { for (int i = 0; i < 5; ++i) { print(i); // Outputs: 0, 1, 2, 3, 4 } }
Decrement Operators
- Pre-decrement (
--variable): decreases the value before usage. - Post-decrement (
variable--): decreases the value after usage.
Usage in a loop:
main
void main() { for (int i = 5; i > 0; --i) { print(i); // Outputs: 5, 4, 3, 2, 1 } }
Task
Complete the code so that it prints all numbers from 2 to 10 inclusive.
main
void main() { for (int i = 2; i <= 10; ___) { print(i); } }
Use an increment operator.
main
void main() { for (int i = 2; i <= 10; i++) { print(i); } }
