Description

Take an integer as the input from the user and then calculate the number of digits in the given input and print it as the output.

Input

3241

Output

4

Input

6

Output

1

C Program

#include <stdio.h>

int main()

{

int num,count=0;

printf("enter the number: ");

scanf("%d",&num);

if(num==0)

printf("digit is 1");

else

{

    while(num!=0)

    {

        num=num/10;

        ++count;

    }

    printf("Number of digits is : %d",count);

}

    return 0;

}

C++ Program

#include <iostream>

using namespace std;

int main()

{

    int num,count=0;

    cout<<"enter the number: ";

    cin>>num;

    if(num==0)

    cout<<"digit is 1";

    else

    {

        while(num!=0)

        {

            num=num/10;

            ++count;

        }

        cout<<"Number of digits is :"<<count;

    }

    return 0;

}

Java Program

import java.util.Scanner;

public class Main

{

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

System.out.print("Enter an Integer: ");

int num = sc.nextInt();

int count = 0;

if(num==0)

System.out.print("Number of Digits = 1");

else{

while(num != 0)

{

count++;

num = num / 10;

}

System.out.print("Number of Digits is "+count);

}

}

}

 

Python

Method -1

num = int(input('Enter an integer :'))

count=0

if(num==0):

    print("Number of digits is 1")

else:

    while(num!=0):

        num=num//10

        count=count+1

    print("Number of digits is ",count)

Method-2

num = int(input('Enter an integer :'))

String = str(num)

print(len(String))
