For Loop

Repeat for specific number of times.

Definition

For loops are a special kind of while loops. They execute some process repeatedly with respect to a change in some counter. Everything that is done using for-loops can be done by while-loops as well.

Syntax

The syntax for for-loops goes as the following:

1. The keyword كرر
2. An open parenthesis (
3. Declaring a counter variable or assigning a value to a declared variable
4. A semicolon ؛
5. The The upper\lower limit of the counter
6. A semicolon ؛
7. The value change that should happen on the counter after each iteration (can be a postfix, prefix, or a binary assignment operation)
8. A closing parenthesis )
9. An opening curly brace {
10. Some code that is to be executed repeatedly
11. A closing curly brace {

Examples

Example 1:

The following example prints the numbers from 0 to 9:

• We are declaring the counter س as a number variable with value 0
• We configured our loop to execute while the value of س is less than 10
• We configured our loop to increment س by 1 after each iteration
• In the body, we are printing the value of س

كرر (متغير رقم س = 0؛ س < 10؛ س++) {
   أكتب(س)؛
}

Example 2:

متغير رقم س؛
كرر (س = 0؛ س <= 10؛ س += 2) {
   أكتب(س)؛
}
