length of number in C++ by R4R Team

Example-
Number is 3245
Length is: 4.
Number is 9087245
Length is: 7

program:

#include < iostream>
using namespace std;
class r4r
{
public:
int func(int n)
{
int count=0;
while(n)
{
n=n/10;
count++;
}
return count;
}
};
int main()
{
int n;
r4r obj;
cout<<"Enter any number"<< endl;
cin>>n;
cout<<"Length is: "<< obj.func(n);
return 0;
}

output-

Enter number
34400
Length is: 5

-In this program, we take a input of the integer number, and for each digit we run the while loop and increase the value of count by (count++) and after loop we have a number of digits in count variable so we return that.
