delete from array

I’m stuck on a C Programming question and need an explanation.

#include <stdio.h>_x000D_
#define N 10_x000D_
_x000D_
int search(int a[], int n, int value) {_x000D_
    int i;_x000D_
    for (i = 0 ;i < n ; i++ ) {_x000D_
        if (a[i] == value)_x000D_
            return i;_x000D_
    }_x000D_
    return -1;_x000D_
}_x000D_
_x000D_
int main() {_x000D_
    int i;_x000D_
    int length, element, value, array[N];_x000D_
_x000D_
    printf("Enter the length of the array: n");_x000D_
    scanf("%d", &length);_x000D_
_x000D_
    printf("Enter the elements of the array: n");_x000D_
    for (i = 0; i < length; i++) {_x000D_
    scanf("%d", &array[i]);_x000D_
    }_x000D_
_x000D_
    printf("Enter the value for searching: n");_x000D_
    scanf("%d", &element);_x000D_
_x000D_
    value = search(array, length, element);_x000D_
_x000D_
    if (value == -1)_x000D_
        printf("%d", -1);_x000D_
    else_x000D_
        printf("%d", value);_x000D_
_x000D_
    return 0;_x000D_
}
_x000D_

Modify the program so that it deletes all instances of the value from the array. As part of the solution, write and call the function delete() with the following prototype. n is the size of the array. The function returns the new size of the array after deletion (The array after deletion will be the same size as before but the actual elements are the elements from index 0 to new_size-1). In writing function delete(), you may include calls to function search(). The main function takes input, calls the delete() function, and displays the output.

int delete(int a[], int n, int value);

Example input/output #1:

Enter the length of the array: 6

Enter the elements of the array: 4 3 1 0 3 9

Enter the value for deleting: 3

Output array: 4 1 0 9
