C++ Program to convert decimal number to binary number

 C++ Program to Find the Binary Value of Decimal Number Using for loop
C++ Code:

1. #include<iostream>
2. #include <stdio.h>
3. using namespace std;
4. int main()
5. {
6.   int n,x,a, c, k;
7.   cout<<"Enter an integer in decimal number system";
8.   cin>>x;
9.   n=x;
10.   cout<<"Binary Value OF Given Number Is: ";
11.  for( a=1;n!=0;a++)
12.   {
13.      n=n/2;
14.   }
15. a=a-2;
16.   for (c = a; c >= 0; c--)
17.   {
18.     k = x >> c;
19.     if (k & 1)
20.       cout<<"1";
21.     else
22.       cout<<"0";
23.   }
24.   return 0;
25. }
