Sorting an Array in Ascending Order

Introduction

• Presenter: Milan Humirev from WeAreEngineer
• Objective: Learn how to sort an array in ascending order using a C program.
• Prerequisites:
  • Understanding of arrays in C programming
  • Knowledge of C if-else statements
  • Familiarity with C for loop

Problem Description

• Implement sorting in a one-dimensional array.
• Example:
  • Input: [45, 56, 12, 22, 34]
  • Output: [12, 22, 34, 45, 56]

Steps to Solve the Problem

1. Array Initialization

   • Create an array of a fixed size, e.g., 7.
   • Use a variable n to store the number of elements in the array.

2. Input Array Elements

   • Ask the user to input array elements.
   • Example: If n = 7, iterate 7 times to input values.

3. Sorting Logic

   • Use a nested loop to compare elements.
   • Each element is compared with elements below it.
   • If an element is greater, it will be exchanged with a smaller one.

4. Program Implementation

   • Initialize variables.
   • Use nested for loops to implement the sorting algorithm.
   • Use a temporary variable to swap elements.

5. Detailed Explanation

   • For i = 0, compare with j = i + 1.
   • Example: Compare 45 with 56.
   • If 45 < 56, no exchange is needed.
   • Continue for all elements.
   • Example: 45 > 12 then swap to make 12 come before 45.

6. Final Loop Iteration

   • Repeat the loop until the entire array is sorted.
   • Example: Final sorted array [12, 22, 34, 45, 56].

Program Execution

• Prompt for number of elements and their values.
• Process the input to produce a sorted array.
• Print the sorted array.

Conclusion

• Successfully sorted the array in ascending order.
