Following C++ program ask to the user to enter any number in binary to convert it into decimal form, then display the result on the screen :
		
#include<iostream.h>
#include<conio.h>
void main()
{
	clrscr();
	long int binnum, decnum=0, i=1, rem;
	cout<<"Enter any binary number : ";
	cin>>binnum;
	while(binnum!=0)
	{
		rem=binnum%10;
		decnum=decnum+rem*i;
		i=i*2;
		binnum=binnum/10;
	}
	cout<<"Equivalent decimal value = "<<decnum;
	getch();
}
