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 :");

Console.Write("Input {0} elements in the array :\n",s1);
for(i=0;i<s1;i++)
{
Console.Write("element - {0} : ",i);
}

Console.Write("Input the number of elements to be stored in the second array :");

Console.Write("Input {0} elements in the array :\n",s2);
for(i=0;i<s2;i++)
{
Console.Write("element - {0} : ",i);
}

/* 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 the number of elements to be stored in the first array :2
Input 2 elements in the array :
element - 0 : 1
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 :
1 2 3 4
