Question

Do it on C++ please

.Question 2: Take a user input integer, and print out the digit by digit. (can enter any positive number, e.g. 123, 34567,37.. (hint: first you need to find the digit of integer, use while loop to find the digit of integer, then look the exercise 6 of lecture 5) Example: . Enter an integer: 123456789 e first digit: 1 o second digit: 2 o ninth digit: 9

Answer 1

code:

#include<iostream>

using namespace std;

int main()

{

int n;

cout<<"Enter an integer: ";

cin>>n;

int sum = 0;

while (n > 0)

{

sum = (sum * 10) + n % 10;

n = n / 10;

}

n = sum;

int i=1;

while (n>0) {

int digit = n % 10;

n = n / 10;

cout << "The digit no. "<<i++<< " is: " << digit << endl;

}

}

or //

#include<iostream>
using namespace std;

void digit(int n)
{
static int i=0;
if(n !=0)
{
digit(n/10);
cout<<"The digit no. "<< ++i <<" is: "<<n%10<<endl;
}

}

int main()
{
int num;
cout<<"Enter an integer: ";
cin>>num;
digit(num);
}

output:

null
