![]() ![]() stdio represents the standard input and output format.īasically, stdio.h is a header file that has the necessary information to include the input/output related functions in our program. Then I will show you the result by running the program.Īs you can see, I included the basic and must needed standard header file in line 1. Let me explain what I did in the code first. Simply follow the code below, and I'll explain all of the steps again below: Our ASCII Calculator using the C programming language Then we'll simply print the ASCII value of the character in the terminal. Then we'll ask the user to provide a character in the terminal.Īfter getting the input from the user, we will assign the value to our character variable. We will declare a character variable first so that we can assign the character to the variable later. This time, we won't assign character values in the character variables. As we want the user to provide the character itself, we will tweak the code a little bit. How to Make an ASCII CalculatorĮarlier we assigned each character manually in our code. If you struggle in doing so, then do not worry as I have you covered. But this might be a hassle if we want something like an ASCII calculator, where the user would provide the character as an input and the code would provide the exact ASCII value as the output in the terminal.ĭo you think you could create that now on your own? Don't scroll down until you have tried to write down the code at least once!Īlright, I hope you have tried to make the calculator by tweaking the code a little bit. In this process, if we want to get the ASCII value of various characters, then we need to change the code manually each time. In all of the code, we assigned character data manually and we checked the ASCII value by printing the value in the output. Now, if you can understand how this works, then let me give you a simple task. ![]() Now, if I run the code, then I would get the ASCII value of a space, which is 32. In line 4, we assigned a space into the character variable named char. So if I use the space in the above code – but this time I use the space instead of the alphabet letter – then the code would be like this: ![]() In code, normally we use a space to represent it, like char ch = ' '. How to Get the ASCII Value of a Space ( )Ī space is also considered a valid character. Well, the good news is that this process works for any valid characters! Let me show you more examples first. As I am only showing you the process of getting the ASCII value of the English alphabet, you may wonder whether the code only works for getting the ASCII value of an alphabet letter or whether it works with any valid characters. Let me introduce you to a more interesting thing now. That is how we get the ASCII value of any character using the above code. In the output, we will get the ASCII value of the character 'A'. If we talk about the integer value of a character, then it can represent one thing – the ASCII value of the character, right? The sample code is given below: Sample input For now, I am taking the character 'A', then I am printing the character itself in line 5.īut if I use %d instead of %c, then I am telling it to print the integer value of the character, not the character itself. In line 4, I am taking a character type data as ch, and I am assigning a character to this variable. Let me give you a nice screenshot below as well: I used the //to indicate the comment here. ![]() Fear not! You do not need to shift to other languages just to get the value using code – you can do that within your C code! Follow the code below: #includeĬan you tell me what we would get in the output? If you think that you would get the character itself in the output, then you are correct! // A Suppose you are writing a C program, and you also need to know the ASCII value of a character. You will never need the internet for searching the ASCII value of any character ever again. No need to panic! In this article, I am going to solve the problem for you. So what would you do if you don't remember the ASCII value of the character you need, and you are also forbidden to search for it on the internet? Like if you are taking an exam, you might be forbidden from accessing the internet during the exam. But sometimes you might not be able to search for them on the internet. Yes, it's true that we can get the ASCII value of any character directly by searching the internet. What do we do in those situations? Most of us simply search for the ASCII value on the internet, like this: This is a common phenomenon in competitive programming, as well – we typically need to use the ASCII value of characters when solving some of the problems on various online platforms like HackerRank, Codeforces, and Codechef. When you're working on a project or computer program, you might need to use the ASCII value of a certain character. ![]()
