Write a Golang program to convert a decimal number to its binary form
Examples
- Input decimal_num = 13 => Output = 8+4+1 => 1101
- Input decimal_num = 11 => Output = 8+2+1 => 1011
Approach to solve this problem
- Step 1: Define a function that accepts a decimal number, decimal_num, type is int.
- Step 2: Define an array to store the remainder while dividing decimal number by 2.
- Step 3: Start a for loop until the decimal number becomes 0.
- Step 4: Print the binary array in reverse order.
Program
package main
import (
"fmt"
)
func decimalToBinary(num int){
var binary []int
for num !=0 {
binary = append(binary, num%2)
num = num / 2
}
if len(binary)==0{
fmt.Printf("%d\n", 0)
} else {
for i:=len(binary)-1; i>=0; i--{
fmt.Printf("%d", binary[i])
}
fmt.Println()
}
}
func main() {
decimalToBinary(87)
decimalToBinary(10)
decimalToBinary(31)
decimalToBinary(0)
}Output
1010111 1010 11111 0
