+C++ Program to convert Decimal to Binary
+We can convert any decimal number (base-10 (0 to 9)) into binary number (base-2 (0 or 1)) by C++ program.
+
+Decimal Number
+Decimal number is a base 10 number because it ranges from 0 to 9, there are total 10 digits between 0 to 9. Any combination of digits is decimal number such as 223, 585, 192, 0, 7 etc.
+
+Binary Number
+Binary number is a base 2 number because it is either 0 or 1. Any combination of 0 and 1 is binary number such as 1001, 101, 11111, 101010 etc.
+
+Let's see the some binary numbers for the decimal number.
+
+Decimal	Binary
+1	0
+2	10
+3	11
+4	100
+5	101
+6	110
+7	111
+8	1000
+9	1001
+10	1010
+
+ 
+Decimal to Binary Conversion Algorithm
+Step 1: Divide the number by 2 through % (modulus operator) and store the remainder in array
+
+Step 2: Divide the number by 2 through / (division operator)
+
+Step 3: Repeat the step 2 until the number is greater than zero
+
+Let's see the C++ example to convert decimal to binary.
+
+#include <iostream>  
+using namespace std;  
+int main()  
+{  
+int a[10], n, i;    
+cout<<"Enter the number to convert: ";    
+cin>>n;    
+for(i=0; n>0; i++)    
+{    
+a[i]=n%2;    
+n= n/2;  
+}    
+cout<<"Binary of the given number= ";    
+for(i=i-1 ;i>=0 ;i--)    
+{    
+cout<<a[i];    
+}    
+}
