c++ program to convert decimal to binary octal and hexadecimal

Write a program that prints a table of the binary, octal and hexadecimal equivalents of the decimal numbers in the range 1 through 256. If you are not familiar with these number systems,

Program:

// The oct, hex, and dec identifiers are stream manipulators
// oct causes integers to be output in octal, the manipulator
// hex causes integers to be output in hexadecimal, and the manipulator
// dec causes integers to be output in decimal.

#include <iostream>
using namespace std;
int main()
{
cout << "Decimal\t\tBinary\t\t\tOctal\tHexadecimal\n";
for ( int loop = 1; loop <= 256; ++loop ) 
{
cout << dec << loop << "\t\t";
// Output binary number
int number = loop;
cout << ( number == 256 ? '1' : '0' );
int factor = 256;
do 
{
cout <<( number < factor && number >= ( factor / 2 ) ? '1' : '0' );
factor /= 2;
number %= factor;
} 
while ( factor > 2 );
// Output octal and hexadecimal numbers
cout << '\t' << oct << loop << '\t' << hex << loop << endl;
}
return 0;
}
