Sort Letters using C++

Sorting the letters of a word is one of the popular use cases for sorting algorithms. Here you will be given a word, or you will have to take a word as user input and sort all the letters of that word in a defined order. So, if you want to learn how to sort the letters of the word using the C++ programming language, then this article is for you. In this article, I will present a tutorial on how to sort letters using C++.

Sort Letters using C++

To sort the letters in a word, we first need to make sure that all letters are in either upper or lower case, as sorting is based on the ASCII value of the letters. To sort letters using the C++ programming language, you need to push the letter with the highest ASCII value at the end of the order. So here’s how you can write a C++ program to sort the letters of a word:

In the code above, I used the bubble sort algorithm which is the simplest sorting algorithm. Below is the complete process of sorting letters of a word using the C++ programming language that I have used in the above code:

  1. I first declared five variables
  2. then I take a word as input
  3. When entering user input, be sure to enter all letters in upper or lower case
  4. After taking the input, I am calculating the length of the input word
  5. And then, I am using nested for loops to compare the ASCII value of the letters and push the letter with a higher value to the end.

Summary

So here is how you can use the bubble sorting algorithm for sorting the letters of a word using the C++ programming language. It is a popular use case for sorting algorithms and can be asked during any coding interview. Hope you liked this article on how to sort letters using C++.
