# C Program to convert Decimal to Binary

Decimal to binary in C: 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 23, 445, 132, 0, 2 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.

5101
6110
7111
81000
91001
101010

## 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 number is greater than 0

Let's see the c example to convert decimal to binary.

Output:

```Enter the number to convert: 5
