In the C programming language

Suppose you are given an array of integers. You want to insert a number x to the array and rearrange so that all the elements are less than or equal to x are before x, and the elements after x are greater than x. For example, suppose the list is {3, 2, 7, 0 1, 5}and x is 4, since3, 2, 0, and 1,are less than or equal to 4,7and 5 are greater than 4, the new array is {3, 2, 0, 1, 4, 7, 5}.The new array has the length of n+1 where n is the length of the input array.

Example input/output #1:

Enter the length of the array: 10

Enter the elements of the array: 3 5 14 03 92 8 11

Enter the number for insertion: 3

Output: 3 1 0 3 2 3 5 4 9 8 11

Example input/output #2:

Enter the length of the array: 8

Enter the elements of the array: 5013 4 1 7 3 5

Enter the number for insertion: 6

Output: 5 0 4 1 356 13 7

1) Name your program arrays.c

2) Include the rearrange( ) function to rearrange the array:

void rearrange(int *a, int n, int insert, int *b);

a represents the input array with length n, and b represents the output array. insert represents the number for insertion. This function should use pointer arithmetic –not subscripting – to visit array elements. In other words, eliminate the loop index variables and all use of the [] operator in the function.

3) In the main function, ask the user to enter the length of the input array, declare the input array. Then ask the user to enter the elements of the array, and the number for insertion. Then call the rearrange function to rearrange and store the elements in array b, then display the output array. 4) Pointer arithmetic is NOT required in the main function.
