Question

What will be an ideal response?

Answer 1

```
#include
#include
#include
using namespace std;

void show( const string message )
{
int integer; // holds values input by user

// prompt user to enter data in decimal format
cout << "\n" << message;
cin >> integer; // store data in integer

// display integer in decimal, octal and hexadecimal format
cout << showbase << "As a decimal number " << dec
<< integer << "\nAs an octal number " << oct << integer
<< "\nAs a hexadecimal number " << hex << integer << endl;
} // end function show

int main()
{
show( "Enter an integer: " );
cin >> oct;
show( "Enter an integer in octal format: " );
cin >> hex;
show( "Enter an integer in hexadecimal format: " );
} // end main
```
Enter an integer: 10
As a decimal number 10
As an octal number 012
As a hexadecimal number 0xa
Enter an integer in octal format: 010
As a decimal number 8
As an octal number 010
As a hexadecimal number 0x8
Enter an integer in hexadecimal format: 0x10
As a decimal number 16
As an octal number 020
As a hexadecimal number 0x10
