## Description

To Count the digits of a given number, divided that number by 10 until that number is greater than 0.

For Each Iteration, divide that number by 10 until the number is greater than 0 and increment the count variable by 1.

For Example:

1923: There are 4 digits.

## C program to count of the digits.

``````#include<stdio.h>
int main(){

int n, count = 0;
printf("Enter the Number : ");
scanf("%d", &n);

while(n>0){
n = n/10;
count = count + 1;
}

printf("Total Digits : %d", count);
return 0;
}``````

## C++ Program to count of the digits.

``````#include<iostream>
using namespace std;
int main(){

int n, count = 0;
cout<<"Enter the Number : ";
cin>>n;

while(n>0){
n = n/10;
count = count + 1;
}

cout<<"Total Digits : "<<count;
return 0;
}``````

Output:

Enter the Number : 1882
Total Digits : 4

## Algorithm of count the digit in a number.

Step 1: SET n and count = 0

Step 3: REPEAT Step 4 and Step 5 while n>0

Step 4: n = n/10

Step 5: count = count + 1

[End Loop]

Step 6: PRINT count

Step 7: EXIT
