# C Exercises: Insert New value in the array (unsorted list )

## C Array: Exercise-14 with Solution

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

Visual Presentation:

Sample Solution:

C Code:

``````#include <stdio.h>

void main()
{
int arr1[100], i, n, p, x;

// Prompt user for input
printf("\n\nInsert New value in the unsorted array:\n ");
printf("-----------------------------------------\n");
printf("Input the size of array : ");
scanf("%d", &n);

// Input values for 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]);
}

// Input the value to be inserted and its position
printf("Input the value to be inserted : ");
scanf("%d", &x);
printf("Input the Position, where the value to be inserted :");
scanf("%d", &p);

// Display the current list of the array
printf("The current list of the array :\n");
for (i = 0; i < n; i++)
printf("% 5d", arr1[i]);

// Move all data to the right side of the array to make space
for (i = n; i >= p; i--)
arr1[i] = arr1[i - 1];

// Insert the new value at the given position
arr1[p - 1] = x;

// Display the array after insertion
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
```
