Golang : Count number of digits from given integer value
Just a simple program to count number of digits from a given integer value. Need this to calculate if an integer value generated by another function has 1 digit, 2 digits or more. If 1 digit, then the signal is weak, if 2 digits, then the signal is normal and if 3 digits or more .. it means the signal is strong.
Here you go!
package main
import (
"fmt"
)
func CountDigits(i int) (count int) {
for i != 0 {
i /= 10
count = count + 1
}
return count
}
func main() {
var i int
fmt.Println("Enter an integer value : ")
_, err := fmt.Scanf("%d", &i)
if err != nil {
fmt.Println(err)
}
fmt.Println("You have entered a : ", CountDigits(i), "digit(s) integer value")
}
