Sort input N Numbers in Ascending Order by using C programming.

Introduction:

Sorting is a fundamental problem in computer science, and it has many practical applications. Sorting N numbers in ascending order is a common task in programming, and there are many algorithms available to accomplish this task efficiently. In this article, we will explore how to sort N numbers in ascending order using C programming language.

Introduction to Sorting:

Sorting algorithms are methods of reorganizing a large number of items into a specific order. The most commonly used sorting algorithms are bubble sort, selection sort, insertion sort, quick sort, merge sort, and heap sort. Each of these algorithms has its strengths and weaknesses, and the choice of algorithm depends on the specific requirements of the problem at hand.

Bubble Sort Algorithm:

Bubble sort is one of the simplest sorting algorithms. It works by repeatedly swapping adjacent elements if they are in the wrong order. The algorithm passes through the array repeatedly until no more swaps are needed, indicating that the list is sorted. 

Program Coding:

Here is the implementation of the bubble sort algorithm in C programming language:

Explanation of the program:

The above program is used to sort N numbers in ascending order. It uses the Bubble Sort algorithm to sort the given input numbers. The steps performed by the program are as follows:

1. The program starts by declaring variables n, i, j, and temp as integers.
2. It then prompts the user to enter the number of values to be sorted and reads the input value into the variable n using scanf.
3. An array of size n is then declared as 'a'.
4. The program then prompts the user to enter n numbers and reads each number into the array 'a' using a for loop and scanf.
5. The outer loop of the program runs n-1 times, which is the number of passes required to sort the array in ascending order.
6. The inner loop of the program runs from i+1 to n-1, which checks and compares each element of the array 'a'.
7. If the value of a[i] is greater than a[j], then the values of a[i] and a[j] are swapped using a temporary variable temp.
8. After completing the inner loop, the sorted array is displayed using another for loop.
9. Finally, the program returns 0 to indicate that the program was executed successfully.

Output of the program:

FAQs

1) What is the Bubble Sort algorithm?

Ans: The Bubble Sort algorithm is a simple sorting algorithm that repeatedly steps through the list to be sorted, compares each pair of adjacent items and swaps them if they are in the wrong order.

2) Why is Bubble Sort used in this program?

Ans: Bubble Sort is used in this program because it is a simple sorting algorithm and is easy to implement in C programming.

3) How do I run this program?

Ans: To run this program, you need to have a C compiler installed on your computer. Save the code in a file with .c extension, compile it, and then run the compiled executable file.

4)What happens if I enter a non-integer value as input?

Ans: The program will not execute properly and may result in an error message as it expects the input to be an integer.

5) Can I sort decimal values using this program?

Ans: No, this program can only sort integer values as it uses the 'int' data type to store the input values.
