Write a C program to delete an element from particular position (given by user ) of the array.

"Before proceeding, new students should understand that programming practice is not limited to only a single file. When you are developing large program, functions can be written in one or more programs and in main program we are using that function by using #include "headerfile.h" on the top of file. Following example is not a large program but is used to demonstrate formerly mentioned idea."

"array.h" (header file)

void input(int *arr,int N)
{
    int i;
    for(i=0;i<N;i++)
    {
        printf("arr[%d]:",i);
        scanf("%d",&arr[i]);
    }
}


void display(int *arr,int N)
{
    int i;
    printf("\n Elements of array are :");
    for(i=0;i<N;i++)
    {
        printf(" arr[%d]:%d" ,i,arr[i]);
        printf("\n");
    }
}

"entry_delete.c" (main file)

#include<stdio.h>
#include "array.h"
#include<stdlib.h>
int cnt=0;
unsigned N;
 void delete(int ar[],int pos)
{
    int i;
    for(i=pos;i<N;i++)
    {
        ar[i]=ar[i+1];
    }
    cnt++;
}
int main()
{   
   
    printf("\nHow many nos. you want to enter:");
    scanf("%u",&N);
    int *ar;
    ar=(unsigned *)malloc(N*sizeof(unsigned));
        int ask=1;
   
    unsigned pos;
    printf("\nEnter the elements of array:\n");
    input(ar,N);
    while(ask==1)
    {
        if(cnt==N)
                        {       printf("\nNo elements to delete");
                                break;
            }
        printf("\nEnter the position-index of array at which you want to delete the entry:");
       
        scanf("%u",&pos);
        if(pos>=N-cnt)
            printf("\nOut of range");
        else
            delete(ar,pos);
        printf("\n\n");
        display(ar,N-cnt);
       
        printf("\nDo you want to delete more elements(1/0):");
        scanf("%d",&ask);
    }
    return 0;
