Decimal to Binary Conversion

“Decimal to Binary Conversion” is one of the classic programming problem exercise for beginners. Here, we are given a decimal number, entered by user and our task is to write a program to convert the given decimal number to its equivalent binary number.

Example (Decimal to Binary Conversion):

7 -> 111
3 -> 11
8 -> 1000

The steps for decimal to binary conversion are as follows:

1. Take Binary = 0, iterator = 1.
2. Store the remainder when the decimal number is divided by 2.
3. Divide the decimal number by 2.
4. Binary = Binary + iterator * remainder.
5. Multiply the iterator by 10.
6. Repeat the steps from 2 to 5 until decimal number is not 0.
7. Print the Binary Number. 

C++ Program for Decimal to Binary Conversion is as follows:

/* C++ Program for Decimal to Binary Conversion */  
#include<bits/stdc++.h>  
using namespace std;  
int main()  
{  
    /* Scan the Decimal Number */  
    int Decimal;  
    cout<<"Enter the Decimal Number: ";  
    cin>>Decimal;  
      
    /* Converting Decimal to Binary */  
    int Binary = 0;  
    int iterator = 1;  
    int temp = Decimal;  
    while(temp != 0)  
    {  
        int remainder = temp % 2;  
        temp = temp / 2;  
        Binary = Binary + remainder*iterator;  
        iterator = iterator * 10;  
    }  
      
    /*Printing the result */  
    cout<<"The Binary of "<<Decimal<<" is "<<Binary;  
}  

OUTPUT:
Enter the Decimal Number: 7
The Binary of 7 is 111
