RANGE

Range Function (range)

The range function in Vint generates a sequence of numbers and is commonly used in loops or for creating arrays of sequential values.

---

Syntax

range(end)
range(start, end)
range(start, end, step)

---

Parameters

• end: The upper limit of the sequence (exclusive).
• start (optional): The starting value of the sequence. Default is 0.
• step (optional): The increment or decrement between each number in the sequence. Default is 1.

---

Return Value

The function returns an array of integers.

Examples

Basic Usage

// Generate numbers from 0 to 4
for i in range(5) {
    print(i)
}
// Output: 0 1 2 3 4

Specifying a Start and End

// Generate numbers from 1 to 9
for i in range(1, 10) {
    print(i)
}
// Output: 1 2 3 4 5 6 7 8 9

Using a Step Value

// Generate even numbers from 0 to 8
for i in range(0, 10, 2) {
    print(i)
}
// Output: 0 2 4 6 8

Generating a Reverse Sequence

// Generate numbers in reverse order
for i in range(10, 0, -1) {
    print(i)
}
// Output: 10 9 8 7 6 5 4 3 2 1

Notes

1. Exclusive End: The end value is not included in the sequence; the range stops before reaching it.
2. Negative Steps: If a negative step is provided, ensure start is greater than end to create a valid reverse sequence.
3. Non-Zero Step: The step value cannot be 0, as it would result in an infinite loop or an error.
