rangeTo() Function

The rangeTo() function is similar to (..) operator. It creates a range up to the value passed as an argument.

Here, we will demonstrate the example of creating an integer range using the rangeTo() function.

Example 1:

fun main(args : Array<String>){
	// creating integer ranges
	println("Integer range 1:")	
	for(x in 1.rangeTo(10)){
		println(x)
	}
	println()

	println("Integer range 2:")	
	for(x in 0.rangeTo(3)){
		println(x)
	}
	println()
}

Output:

Integer range 1:
1
2
3
4
5
6
7
8
9
10

Integer range 2:
0
1
2
3

Example 2:

fun main(args : Array<String>){
	// creating integer ranges
	println("Integer range 1:")	
	for(x in 1.rangeTo(10) step 2){
		println(x)
	}
	println()

	println("Integer range 2:")	
	for(x in 0.rangeTo(5) step 2){
		println(x)
	}
	println()
}

Output:

Integer range 1:
1
3
5
7
9

Integer range 2:
0
2
4
