# C program: convert Octal Number to Hexa-Decimal Number

To covert Octal Number to Hexa-Decimal Number in C programming , It is very easy. I will tell you the easiest way without any function without Array[] .You think How ? ok..let's read the post We all know about Ocatal and Hexa- decimal Number.Hexa-Decimal Number has 16 base(0-F) and Octal Number has 8 base(0-7 digit).

As the same process we use in c programming .Hope you know basic C program . In C program we use '%c' for any character . Same we use here '%x' for Hexa- decimal and '%o' for octal Number. It is the easiest way to convert Octal to Decimal.
In this post we will learn , how to convert Octal Number to Hexa-Decimal Number by c programming. From above we get some basic knowledge about Octal to Hexa-Decimal .

### See the table of octal and Hexa-decimal number . You get a clear idea about the octal and Hexa-decimal number.

 Hexa-Decimal Octal 0 0 1 1 2 2 7 7 8 10 9 11 A 12 B 13 C 14 D 15 E 16 F 17 1A 32 1F 37

## Let's learn , How to convert Octal Number to Hexa-Decimal Number through a problem.

It is a good practice any program through the problem,It will help to remember the program and better understand the program.When you learn something always try to implement.

Let Suppose a problem is :

# Any input through the keyboard . Write a program to convert Octal to Hexa-Decimal Number in C ?.

>>To solve this problem ,

>>> we have to take '%x' for Hexa-decimal and '%o' for octal Number.
It is the easy way to convert Hexa-Decimal Number to Octal Numberr.
You have many qustion , many doubts right now.I will cleare all.

If I input '1A' as a hexa decimal number, it's octal value is 32 . If you run the program and give any hexa decimal number and hit enter button you will get octal number.

Let's Go to the code :

Note :Click on the button to copy the text from the text field. Try to paste the text (e.g. ctrl+v) afterwards in a different window, to see the effect.

write the above code in your compiler or copy this code and paste . save this with '.c ' extension.In this screen User have to input a number to convert Octal Number to Hexa-Decimal Numberr .First input a Octal value Then press Enter to show Hexa-Decimal value.
