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.
| Decimal | Binary |
|---|---|
| 1 | 1 |
| 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 number is greater than 0
Let’s see the c example to convert decimal to binary.
Output:
Enter the number to convert: 5 Binary of Given Number is=101
