Answer to Question #180483 in C++ for PAVITHRA

Question

Param is a course instructor of 

c++ programming and currently 

he is teaching conversions to his 

students. He started with the 

basic programs and now he 

want to introduce some 

complex problems. Before 

starting the complex problems, 

he wants to start with high 

difficulty level problem, such as: 

counting the digits of a number. 

Help Mr. param to write a 

program which will accept one 

integer argument and returns 

count of digits of that argument 

using class to basic conversion.

Answer 1

#include <iostream>
#include <string>
using namespace std;


class CounterDigit{
private:
	long int number;
public:
	//Constructor
	CounterDigit(long int number){
		this->number=number;
	}
	//class to basic conversion
	operator int(){
		int counter = 0;
		while (number != 0){
			number = number / 10;
			counter++;
		}
		return counter;
	}
};


int main(){
	long int number;
	//Read the number
	cout<<"Enter the number: ";
	cin>>number;
	//create CounterDigit object
	CounterDigit counterDigit(number);
	cout<<"Number of digits: "<<counterDigit<<"\n";


	system("pause");
	return 0;
