C# Sharp Exercises: Merge two arrays of same size sorted in ascending order

C# Sharp Array: Exercise-7 with Solution

Write a program in C# Sharp to merge two arrays of same size sorted in ascending order.

Sample Solution:-

C# Sharp Code:

using System;  
public class Exercise7
{  
    public static void Main() 
{
	int[] arr1 = new int[100];
	int[] arr2 = new int[100];
	int[] arr3 = new int[200];
    int s1, s2, s3;
    int i, j, k;
	
	
       Console.Write("\n\nMerge two arrays of same size sorted in ascending order.\n");
       Console.Write("------------------------------------------------------------\n");	
	   
       Console.Write("Input the number of elements to be stored in the first array :");
	   s1 = Convert.ToInt32(Console.ReadLine()); 	   
   
       Console.Write("Input {0} elements in the array :\n",s1);
       for(i=0;i<s1;i++)
            {
	      Console.Write("element - {0} : ",i);
	     arr1[i] = Convert.ToInt32(Console.ReadLine()); 		  
	    }


       Console.Write("Input the number of elements to be stored in the second array :");
	   s2 = Convert.ToInt32(Console.ReadLine()); 	   
   
       Console.Write("Input {0} elements in the array :\n",s2);
       for(i=0;i<s2;i++)
            {
	      Console.Write("element - {0} : ",i);
	     arr2[i] = Convert.ToInt32(Console.ReadLine()); 		  
	    }

    /* size of merged array is size of first array and  size of second array */
    s3 = s1 + s2;
     
/*----------------- insert in the third array------------------------------------*/
    for(i=0;i<s1; i++)
        {
            arr3[i] = arr1[i];
         }
     for(j=0;j<s2; j++)
        {
            arr3[i] = arr2[j];
            i++; 
        }
/*----------------- sort the array in ascending order ---------------------------*/
   for(i=0;i<s3; i++)
        {
           for(k=0;k<s3-1;k++)
             {
         
                if(arr3[k]>=arr3[k+1])
                 {
                   j=arr3[k+1];
                   arr3[k+1]=arr3[k];
                   arr3[k]=j;
                 }  
              }
         }                      
/*--------------- Prints the merged array ------------------------------------*/
    Console.Write("\nThe merged array in ascending order is :\n");
    for(i=0; i<s3; i++)
    {
        Console.Write("{0} ", arr3[i]);
    }
	Console.Write("\n\n");
  }
}

Sample Output:

Merge two arrays of same size sorted in ascending order.                                                      
------------------------------------------------------------

Input 2 elements in the array :

element - 1 : 2                                                                                               
Inpu2 the number of elements to be stored in the second array :2                                              
Input 2 elements in the array :                                                                               
element - 0 : 3                                                                                               
element - 1 : 4                                                                                               
The merged array in ascending order is :
