Count Sort using C++

The time complexity of count sort is better than the other sorting techniques. In this article, I will take you through the implementation of the Count Sort using C++ programming language.

Count Sorting

The count sort algorithm works by finding the number of each unique element in the array. Then it calculates the position of each element in a sorted array. The only limitation of the counting sort is that it is limited to small positive integers only.

Count sorting is used to sort a collection of objects based on keys. This algorithm is only used on integers, so we can say that it is an integer sorting algorithm.

Because count sorting only uses key values as the index of an array, it cannot be used to compare values inside an array.

Count Sort using C++

Now let’s see how to implement the count sort using the C++ programming language. Let’s take a look at the steps to implement this algorithm:

  1. First, create an array that is populated by spelling out all of the elements in the original array according to the number of times they appear in an unsorted array.
  2. Then add the values to the completed count table.
  3. Then move around the array, incrementing the index of each value by one.
  4. Finally, you need to iterate through the original array, but be sure to increment the count array while sorting.

Now let’s implement the above steps to see how to sort an array by using the count sort technique using C++:

So this is how to implement the counting sort algorithm in C++. I hope you liked this article on how to implement the counting sort using C++. Feel free to ask your valuable questions in the comments section below. You can learn the complete C++ programming language from here.
