Write program segments that accomplish each of the following:

a) Calculate the integer part of the quotient when integer a is divided by integer b.
b) Calculate the integer remainder when integer a is divided by integer b.
c) Use the program pieces developed in (a) and (b) to write a function that inputs an integer between 1 and 32767 and prints it as a series of digits, each pair of which is separated by two spaces. For example, the integer 4562 should print as follows:

4 5 6 2

```
// Print input number as series of digits,
// each pair of which is separated by two spaces.
#include
using namespace std;

int quotient( int, int ); // function prototype
int remainder( int, int ); // function prototype
void printDigits( int ); // function prototype
int main()
{
int number; // input number

do
{
cout << "Enter an integer between 1 and 32767: ";
cin >> number;
} // end do
while ( number < 1 || number > 32767 );

cout << "The digits in the number are:\n";
printDigits( number ); // call function to print digits
cout << endl; // add trailing newline
} // end main

// Part A: determine quotient using integer division
int quotient( int a, int b )
{
return a / b;
} // end function quotient

// Part B: determine remainder using the modulus operator
int remainder( int a, int b )
{
return a % b;
} // end function remainder

// Part C: print digits of an integer separated by two spaces
void printDigits( int number )
{
int divisor = 10000; // current divisor

// prevent leading zeros from being printed
while ( number < divisor )
divisor = quotient( divisor, 10 );

// determine and print each digit
while ( divisor >= 1 )
{
// use quotient to determine current digit
cout << quotient( number, divisor ) << " ";

// update number to be remainder
number = remainder( number, divisor );

// update divisor for next digit
divisor = quotient( divisor, 10 );
} // end while
} // end function printDigits
```
