Course Introduction
Programs for practice
In the program below, we've introduced beginers to programming in C++
Source Code:Convert Binary to Decimal
/* C++ Program - Binary to Decimal */
#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();
}
Output
Enter any binary number :10100
Equivalent decimal value = 12
