Write a program in C to insert values in the array (unsorted list).

Pictorial Presentation:

Sample Solution:

C Code:

#include <stdio.h>

void main()
{
   int arr1[100],i,n,p,x;
   
       printf("\n\nInsert New value in the unsorted array : \n ");
       printf("-----------------------------------------\n");   
       printf("Input the size of array : ");
       scanf("%d", &n);
    /* Stored values into the array*/
       printf("Input %d elements in the array in ascending order:\n",n);
       for(i=0;i<n;i++)
            {
	      printf("element - %d : ",i);
	      scanf("%d",&arr1[i]);
	    }
	
	
   printf("Input the value to be inserted : ");
   scanf("%d",&x);
   printf("Input the Position, where the value to be inserted :");
   scanf("%d",&p);
   
   printf("The current list of the array :\n");
   for(i=0;i<n;i++)
      printf("% 5d",arr1[i]);   
   /* Move all data at right side of the array */
   for(i=n;i>=p;i--)
      arr1[i]= arr1[i-1];
   /* insert value at given position */
      arr1[p-1]=x;

 
   printf("\n\nAfter Insert the element the new list is :\n");
   for(i=0;i<=n;i++)
      printf("% 5d",arr1[i]);
	  printf("\n\n");
}

Sample Output:

Insert New value in the unsorted array :                                                                      
 -----------------------------------------                                                                    
Input the size of array : 4                                                                                   
Input 4 elements in the array in ascending order:                                                             
element - 0 : 1                                                                                               
element - 1 : 8                                                                                               
element - 2 : 7                                                                                               
element - 3 : 10                                                                                              
Input the value to be inserted : 5                                                                            
Input the Position, where the value to be inserted :2                                                         
The current list of the array :                                                                               
    1    8    7   10                                                                                          
                                                                                                              
After Insert the element the new list is :                                                                    
    1    5    8    7   10
