# 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:

- Take Binary = 0, iterator = 1.
- Store the remainder when the decimal number is divided by 2.
- Divide the decimal number by 2.
- Binary = Binary + iterator * remainder.
- Multiply the iterator by 10.
- Repeat the steps from 2 to 5 until decimal number is not 0.
- 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; }

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