In this tutorial, we will write a C Program to Convert a Binary Number to Hexadecimal Number. Before that, you must have knowledge of the following topics in C.

### Binary number

The binary numbers are based on 0 and 1, so it is a base 2 number. They are the combination of 0 and 1. For example, 1001, 110101, etc.

The hexadecimal number is represented with a base of 16. It has digits from 0 to 15 to represent, However after 9 the values are represented in Alphabet till 15 such as 10 is represented as A, 11 as B, 12 as C, 13 as D, 14 as E, and 15 as F.

`Input: 11011111 Output: DF Input: 10001101 Output: 8D`

Now let us go through a program for Binary to hexadecimal conversion in C.

## C Program to Convert Binary to Hexadecimal

Output:

`Enter a Binary number: 10001101Equivalent Hexadecimal number: 8D`
