Split number into digits in backward direction (C++)

Split number in backward direction

split_nb() splits the number into digits in the backward direction and it takes 1 parameter:

num takes the value which you want to split into digits.

num takes the value between 1 to 10 digits because its data type is integer.

Code

#include "stdafx.h"

#include "iostream"

#include "conio.h"

#include "iomanip"

#include "math.h"

using namespace std;

void split_nb(int num)

{

  int x=0,y=0,count=0;

  char tempStr[11];

       itoa ( num , tempStr , 10 );

       while(count!=strlen(tempStr))

       {

              x=num/10;

              y=num%10;

              num=x;

              count++;

              cout<<setw(3)<<y;

       }

}

int main()

{

       split_nb ( 1 );cout<<endl;

       split_nb ( 12 );cout<<endl;

       split_nb ( 123 );cout<<endl;

       split_nb ( 1234 );cout<<endl;

       split_nb ( 12345 );cout<<endl;

       split_nb ( 123456 );cout<<endl;

       split_nb ( 1234567 );cout<<endl;

       split_nb ( 12345678 );cout<<endl;

       split_nb ( 123456789 );cout<<endl;

       split_nb ( 1234567890 );cout<<endl;

      

       _getche();

       return 0;

}
