C Program For Hexadecimal to Decimal Conversion

Here we will build a C program for hexadecimal to decimal conversion using 5 different approaches i.e.

1. Using format Specifier
2. Using Switch case
3. Using array 
4. Using while loop
5. Using for loop

We will keep the same input in all the mentioned approaches and get an output accordingly.

Input: 

hexanumber = "2D" 

Output: 

decimalnumber = 45

Method 1: Using format specifier

The format specifier %x represents the Hexadecimal number

Output

Method 2: Using switch case

Decimal value is: 45

Method 3: Using Array

Decimal Number : 45

Method 4: Using while loop

Hexadecimal number = 2D
Decimal number = 45

Method 5: Using for loop
