C Program For Hexadecimal To Binary Conversion
Let us learn how to write a code for hexadecimal to binary conversion in C programming language. This C program to convert hexadecimal number into binary value makes use of a switch case. The switch method includes a case for every digit of the hexadecimal number system.
Hexadecimal Number System
The hexadecimal number system is also known as Hex. The base of a hexadecimal number is 16. Therefore, it includes a total of 16 symbols including numbers and characters.
The symbols acceptable in a hexadecimal number system are as follows:
A, B, C, D, E, F, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0
where, A = 10, B = 11, C = 12, D = 13, E = 14, F = 15.
Example
(F12E)16 = (1111 0001 0010 1110)2
Every character or number in a hexadecimal number system has a particular value in binary number system. All you need is to match that value with the binary number format.

Such a simple Hex to Decimal Number conversion c program. Switch cases makes it so easy to solve it. Thanks.
You’re welcome. Actually Hexadecimal to Binary conversion programs are quite simple to understand if done using switch cases.
