C++ Program to Convert Decimal Number to Binary

Normally, when we work with Numbers, we use primitive data types such as int, short, long, float and double, etc. The number data types, their possible values and number ranges have been explained while discussing C++ Data Types.

Here is source code of the C++ Program to Convert Decimal Number to Binary. The C++ program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.

SOURCE CODE : :

/*  C++ Program to Convert Decimal Number to Binary  */

#include<iostream>

using namespace std;

int main()
{
    int d,n,i,j,a[50];
    cout<<"Enter any Decimal number :: ";
    cin>>n;

    cout<<"\nThe binary conversion of [ "<<n<<" ] is 1";

    for(i=1;n!=1;++i)
    {
        d=n%2;
        a[i]=d;
        n=n/2;
    }

    for(j=i-1;j>0;--j)
        cout<<a[j];

    return 0;
}

OUTPUT : :

/*  C++ Program to Convert Decimal to Binary  */

Enter any Decimal number :: 1234

The binary conversion of [ 1234 ] is 10011010010

Process returned 0
