#include<conio.h>
void main()
{
	clrscr();
	long int i=0;
	char binnum[100], hexdec[100];
	cout<<"Enter any hexadecimal number : ";
	cin>>hexdec;
	cout<<"\nEquivalent Binary value is : ";
	while(hexdec[i])
	{
		switch(hexdec[i])
		{
			case '0' : cout<<"0000";
				break;
			case '1' : cout<<"0001";
				break;
			case '2' : cout<<"0010";
				break;
			case '3' : cout<<"0011";
				break;

			case 'd' : cout<<"1101";
				break;
			case 'e' : cout<<"1110";
				break;
			case 'f' : cout<<"1111";
				break;
			default : cout<<"\nInvalid hexadecimal digit "<<hexdec[i];
		}
		i++;
	}
	getch();
}
