Answer 1

using namespace std;

#include <iostream>

#include <stdio.h>

//method #1: using standard and modular division

DigitsV1(int x)

{

int iTens = x%100;

cout << " The hundreds place is " << x/100 << endl;

cout << " The tens place is " << iTens/10 << endl;

cout << " THe ones place is "<< iTens%10 << endl;

}

//method #2: using a string

DigitsV2(int x)

{

char buff[25];

sprintf(buff,"%d",x);

cout << "The hundreds place is " << buff[0] << endl;

cout << "The tens place is " << buff[1] << endl;

cout << "the ones place is " << buff[2] << endl;

}

Go()

{

int iNum=0;

cout << "Please input the 3-digit number :> ";

cin >> iNum;

DigitsV1(iNum);

cout << "--------------------------------------" << endl;

DigitsV2(iNum);

}

main() { Go(); }
