In this article, we will learn to write Kotlin program to Convert a Decimal Number to Binary and count the number of 1s in Kotlin.
Program Code:
Program Code:
import java.util.Scanner
fun main(args: Array) {
var n: Int
var count = 0
var a: Int
var x = ""
val s = Scanner(System.`in`)
print("Enter any decimal number:")
n = s.nextInt()
while (n > 0) {
a = n % 2
if (a == 1) {
count++
}
x = x + "" + a
n = n / 2
}
println("Binary number:$x")
println("No. of 1s:$count")
}
Output:fun main(args: Array
var n: Int
var count = 0
var a: Int
var x = ""
val s = Scanner(System.`in`)
print("Enter any decimal number:")
n = s.nextInt()
while (n > 0) {
a = n % 2
if (a == 1) {
count++
}
x = x + "" + a
n = n / 2
}
println("Binary number:$x")
println("No. of 1s:$count")
}
Enter any decimal number:123
Binary number:1101111
No. of 1s:6
Description:Binary number:1101111
No. of 1s:6
In the program source code, it takes input from a user to enter any decimal number. Next step is to convert the entered decimal number into a binary number with the help of division and modulus operations along with if conditions and for loop to achieve the desired output.
